The given questions are:

A) (square root of x)- 1 = 3

Solution: This can be written as:

- 1 = 3

Adding one to both sides of the above equation, we get:

= 3 + 1

==> x =

==> x = 16

B) (square root of xcubed) = 8

Solution: This can be written as:

= 8

==> =

==> = 64

==> x =

==> x = 4

Hence, the solution.

C. cubed (square root of x squared) = 4

Solution: The given expresion can be written as:

= 4

= 4 (since Sqrt(x^2) = x )

==> x =

Hence, the solution.

Happy calculating :))
