10 points, Solve the rational exponents, please show the work if you can :) please don't use me for points, its already happened twice today.


2^(x) = 128, 5^(x) = 15,625, 8^(x) =4096, 3^(x) =6561, 8^(x) =262,144, 5^(5x) =3125, 7^(x) =2401, 7^(3x) = 117,649, and 9^(x) =729

Essentially just turn the big number into an exponent so u can cancel out and be left with just the x for example 128 is the same as 2^7 and when you have it like that you simply cancel the 2 and are left with x=7

A) x=7
B) x=6
C) x=4
D) x=8
E) got cut off theres no value
F) x=2
G) x=3

Id reccomend downloading photomath for these type of questions or symbolab on your phone it shows the steps but try practicing it first :)
