MATH HELP...!! URGENT...
Deep:
For the 1st 1..
U don't really ahve to use log.. I just realised that..
It's pretty simple in fact
32 = 2^5
n Root of 32 = 32^(1/n)
Implying that 2^(5/n) = 8
Now, 8 = 2^3
=> 32^(1/n) = 2^(5/n) = 8 = 2^3
2^(5/n) = 8 = 2^3
=>> Equating the powers of 2
5/n = 3
n = 5/3
This method is useful if you are not allowed the use of a calculator
