The answer is not 2.
2 mutliplied by itself once is 2x2 = 4 22
2 mutliplied by itselft twice is 2x2x2 = 8 23
2 mutliplied by itself three times is 2x2x2x2 = 16 24
2 mutliplied by itself four times is 2x2x2x2x2 = 32 25
x multiplied by itself n times is x(n+1)
So, if x is multiplied by itself five time, this is x6
So, x6 equals 32
or x equals 6√32
