Answer 1

Explanation:

Hey there!

Given;

`{2}^(4x - 1) =32`

`{2}^(4x) . {2}^( - 1) = {2}^(5)`

`{2}^(4x) . (1)/(2) = {2}^(5)`

`{2}^(4x) = {2}^(5) . {2}^(1)`

`{2}^(4x) = {2}^(6)`

`4x = 6`

`x = (6)/(4)`

`x = (3)/(2)`

7.)

`√(x) - 3 = 7`

`√(x) = 7 + 3`

`( { √(x)) }^(2) = {(10)}^(2)`

X= 100

8.)

`( {x + 1)}^(2) = 81`

`(x + 1) = √(81)`

`x + 1 = \sqrt{ {9}^(2) }`

`x + 1 = 9`

`x = 9 - 1`

X=8

Hope it helps...
