@Term pak guy
U've got any formula a broda can use to ascertain what power to raise a number to to give another number.

E.g. 3 raise to x will gimme 4374
How do I find x?

every multiple of 3 by 3 should end with 1 ,3 ,7 or 9.


lets take 3^x =729 for example.


729/3= 243*3 ---1

243/3= 81 *3 -------2

81/3= 27*3----3

27/3= 9*3---4

9/3= 3*3----5

3/3= 1x 3---6


x= 6
i.e its a GP

or

T= a x r ^ (n-1)

T= 243

a= 3

r= 3

n= ??

729= 3x 3^(n-1)

729/3= 3^ (n-1)

243 = 3^ (n-1)

243/3 * 3 = 3^ (n-1)

81* 3= 3^ (n-1)

81/3 *3 *3= 3^ (n-1)

27*3*3 = 3^(n-1)

27= 3*3*3

3*3*3*3*3= 3^(n-1)

3^5= 3^(n-1)

3 cancel 3

5= n-1

n= 6.

thus, 3^6= 729.

How do u expect me to get those values without calculator @bolded?

4374 is not a perfect cube of 3 na.

medwhite0:
N / N o = (1/2 ) ^t/T N = quantity left behind No= original quantity T= half life t= Total time taken

2 x 10"6/ 8*10" 6 = (1/2)" t/T 1/4 =( 1/2) "t/T
1/4 is same as 1/2 "2
(1/2)"2 = (1/2) " t/T
1/2 cancel 1/2
2= t/T 2T = t and t= 64
2T= 64 T = 32mins

RobinHez:
Erm...guys no vex, I forgot how to do this thing again.

The number of atoms of a radioactive substance is initially 8x10¹⁶. If the number reduces to 2x10¹⁶ in 64 mins. What is the Half life of the substance?

A. 82 mins
B. 16 mins
C. 8 mins
D. 4 mins

Abeg! Na how u take do am I dey fine...I don loss my formula book

N / N o = (1/2 ) ^t/T
N = quantity left behind
No= original quantity
T= half life
t= Total time taken

this fear flies na die oo
