Question

Help pls :( im so close to having a c

Answer 1

x=2

Explanation:

First we can find out what
`((1)/(81) )^(2)` in terms of 9 is...

`(1)/(81) ^(2)=(1^(2))/(81^(2)) =(1)/(81^(2)) =(1)/(9^(4))`

This means we need 3x-10 to be equivalent to -4 as
`9^(-4)` is equivalent to
`(1)/(9^(4))`.

3x-10=-4

Add 10 to both sides

3x=6

Divide both sides by 3

x=2
