Question

Which of the following is a radical equation? x + StartRoot 5 EndRoot = 12 x squared = 16 3 + x StartRoot 7 EndRoot = 13 7 StartRoot x EndRoot = 14

Answer 1

the answer is A

Explanation:

Answer 2

x = 3

Explanation:

`(8x-8)^(3/2)=64`

Multiply both sides by the exponent 2/3.

`8x - 8 = 64^(2/3)`

Solve for the exponent.

`8x-8=16`

Add 8 to both sides.

`8x = 16+8`

`8x=24`

Divide 8 into both sides.

`x=24/8`

`x=3`
