9 to the eighth power = 43046721
9.1136 x 10^8
if x8 = 20 then x = - eighth root of 20 or x = eighth root of 20 eighth root of 20 = 1.4542154.... Maybe you mean 8x = 20 If so Ln (8x) = Ln (20) => x Ln(8)= Ln(20) => x = Ln(20)/Ln(8) = 1.4406426...
five eighth 1/4 = 2/8 3/8 + 2/8 = 5/8

eighth root of 10 = 10 to the 1/8 power = 1.33
It is: 1/8 to the power of 5 = 1/32768
6-8 equals 5.95374181e-7
Is is called the exponent.
