. Pls much effort hd been made to solve this problem. Only r is obtainable pls if u know the first term help pls

You question is seemingly inconsistent.

For a G.P the ratio of T5 to T2 is always r3.

Therefore I can't figure out why T2 is 1/24 of T5.

Kindly double check the question. Is there something I'm missing?

Also note that knowing the ratio of terms in GP cannot give us the value of the first term, I think more information are needed

@OP. I quite agree with billy187. Subaru is a reliable on- and off-roader that will surprise you on trial. It's Japanese so parts aren't much of an issue. The make is quite popular as it has been around for as long as i can remember so it's not a strange ride if you are in Lagos. But i'd suggest the I4 engine type version (1.6 - 1.8L). It's OK if you consider the auto tranny option, but I won't advise you go for the V6 - it's a 3.0 L guzzler, and you may not find good mechos for that version. Consider a straight tokunbo - not naija-used and you'll enjoy your money. Good luck!

Do you have any for sale??

With a budget of 600K you are also looking for luxury? I suggest you look at the Toyota Matrix...4 wheel drive....that may be the best.

Thıs observatıon ıs especıally for u is prime where u is the power of exponetial expression for which the total number of digits are to be found, try 3^129, 3^17 though logk<1 but there are cases where logk is very close to 1, thus altering the actual approximation of the number of digits
Yes, I must admit there are cases where it is extremely close. But I don't think there exist a situation where it is actually 1.

There's an exception though. When the index is 1. e.g 1250 grin

For the instances above:

3129 has 62 digits.

129log3 = 61.5486... (Rounded up, we have 62) valid

317 has 9 digits.

17log3 = 8.111... (Rounded up, we have 9) valid

It must be neatly used with excellent interior and exterior conditions.
The Engine must be well maintained and confirmed to be in perfect condition.

I sincerely appreciate your pieces of advice.
My job requires that I travel the depth of my state daily (at least 3 in 7) approx. 250km
Note that the nature of some of the roads are unpleasant and therefore may eventually leads to wheel problems. I am also going to be using this car for personal runnings so I'm not really considering anything Van-like.
What I need is something that balance luxury with durability.

Thanks

Good Morning Nairalanders,
I have a budget of about 600k. I would love to buy a Nigerian used car or Tokunbo around that price range. The issue I have is that I want a car that will be durable and will be able to traverse rough terrains with minimal injuries.
This is my first. I am getting this car due to the nature of my new job.

Kindly advice accordingly. Thanks in advance

Pls solve

1)1/8.7^-3=y^3
find y

2)(root5-2)^2-z=(1-root20)^2.
find z

Correct the questions if I'm mistaken.

1.

1/8 * 7-3 = y3

2-3 * 7-3 = y3

(2*7)-3 = (1/y)-3

2*7 = 1/y

y = 1/14


2.


(√5 -2)2 - z = (1 - √20)2

z = (√5 -2)2 - (1 - √20)2

z = 5 - 4√5 + 4 - 1 + 2√20 - 20

z = -12 - 4√5 + 2√20

z = -12 - 4√5 + 4√5

z = -12

DatechMan:

The answer should be:

5000log3

which is 2385.60627...

Since there can only be whole digits(always round up), the answer is 2386

Explanation:

35000 == k x 10n

where n represent the number of digits if 0.1< k < 1

finding log of both sides and simplifying:

5000log3 = logk + nlog10

n = 5000log3 - logk

since logk is inconsequential since logk <<< 5000log3, we can ignore first.

n = 5000log3
n = 2385.60627...

Note that -1 lessorequal logk lessorequal 0

Therefore we can only round up our answer

n = 2386


Also, by extension:

logk = 5000log3 - 2386

k = 10(5000log3 - 2386)
k = 0.40389976...

It follows that 35000 = 0.4039 x 102386

benji93:

Well you might be or not be exactly right it could be 2385, i am trying to verify that, there are cases of application of the formula were approximating it gives u a number 1 less or 1 more than exact, but you don try respect

It is not an assumption. Check the solution again.

Note:

0.1< k ≤ 1

Therefore -1 ≤ log k ≤ 0

This implies that we will always round up

Good evening sirs!!!!!! ... Need ur help. Kindly simplify 1 . log(-i) 2. Sin i where i is a complex no.



1.
Changing -i to polar form. We have e(3π/4)i.

Therefore log(e(3π/4)i) = 3π/4 i

Note that generally speaking. The answer is 3π/4 ± n2π

2.
Using complex form of Sine (Euler). i.e

Sin x = (exi - e-xi)/2i

Therefore we have

Sin i = (eii - e-ii)/2i

Sin i = (e-1 - e1)/2i

= (1 - e2)/2ei
