Work out the value of 2^5

2^5 means 2 to the fifth power, or 2^2^2^2^2.

2^5=

2*2=4

4*2=8

8*2=16

16*2=32

Hence, 2^5=32

32

Step-by-step explanation:

is the same as 2*2*2*2*2

2*2*2*2*2 is 32

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
