Hi, pls I need a mathematician to tutor me. Am an OOU student. Tnx

what level /aspects. of mathematics ?

mode of tutoring ? ( online or physical )

tutoring to pass exams or improve knowledge ?

DatechMan:
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

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

Good Morning Nigeria

#GodBlessNigeria
[quote author=benji93 post=42432099]Oh isee thts ur idea of rounding up
and ofcourse not there is never a case where it is 0.1 or 1 exactly
it comes from the idea that it comes from the fact that every exponential expression a^b>1 is such that 10^n-1<a^b>10^n infact it was from this axiom i thought that a^b could be at any point at infinity very close to the lower boundary or the upper boundary, if it is very close to the upper boundary, where logk <1 normally based on your rounding up if you had n=999.62 forexample it would be 1000 but actually if the value of k is to considered you could have 999.62 + 0.4 which gives 1000.02 which should be approximated to 1001 somehow we would not be able to test all numbers to infinity, but we can test as many number of digits as possible, i am not trying to disprove you bro,i am just saying based on my assumption there is a possibilty of having that +-1 problem somewhere at infinity unless my assumption is wrong which is also another possibility...

i must commend u 4 dis work sir, its the most significant work on this thread 4 more than a year now, ur idea is good but i wish to make a few corrections, Basically the part u find difficult to answer; "when to add 1, subtract 1 or approx.", on that note, u should b aware that BENJI93 is also very much on track!!!

Let it be required to find the number of digits in d^c NOTE; the limitation of ur proof subconsciously assumes that "d" must be a unit digit. Here is a proof that removes that assumption
now d^c=d^cx10^c/10^c

=(d/10)^cx10^c

let (d/10)^c=u, then if d is a unit digit, ur inequality 0.1<d<1 is obviously satisfied, otherwise it fails. So lets remove ur UNCOUNSCIOUS assumption by letting "d" be an r-digit number. Then d=kx10^r-1 where 1<k<10, so u=(0.kx10^r-1)^c=0.k^cx10^(r-1)c

hence, d^c=0.k^cx10^(r-1)cx10^c=0.k^cx10^rc. Suppose we let m=0.k^c, then since m=10^logm we have; d^c=10^logmx10^rc=10^rc+logm, From this we conclude that the number of digits in d^c are precisely 1+rc+clog0.k [or 1+(r-1)c+clogk); if the first digit of the base number is 1 (one) then, there are precisely 1+(r-1)c digits and that is the only case where we know the result precisely (without using calculator). Finally, the number of digits of d^c is greater than 1+(r-1)c, where r is the number of digits in d.

For example, if we denote "N" by the number of digits in d^c, then;
for 11², N=1+1x2=3
for 100², N=1+2x2=5

Interesting fact: For all pythagorean triples, the product of the terms of each triple is always a positive integer multiple of the sum of the terms

yeah, I agree to an extent but, what about this, 0,-1 and 1?

Ofcourse i was talking about the class of pythagorean triples (a,b,c) beginning with the terms (3,4,5). where a,b,c is a subset of Z+.My assertion is always thru for this case. I am now trying to prove if there are any two pythagorean triples, in which the product of their terms are the same

Pls statisticians in d houses I need you on this;
Given x success in trials,find the maximum likelihood estimate of the parameter p of the binomial distribution given by the probability mass function (x;n,p)=( formula of binomial distribution) for x=0,1,2...,n
(answer p^=x^/n)
p^ ,x^=p cap,x cap.

help solve this if 1 is added to both numerator and denominator of a fraction,the fraction becomes 1/2. If 8 is added to both, the fraction becomes 2/3. What is the fraction?

let the fraction be x/y.
(x+1)/(y+1)=1/2.
(x+ cool

/(y+

=2/3.
Solve the equations simultaneously to get x and y.
