Make "a" the subject form this formula: √(a) = b

Question

Make "a" the subject form this formula:

`√(a) = b`

Answer 1

`a=b^(2)`

Explanation:

square both equations:

`√(a)^{} =b^{}`

`√(a)^(2) =b^(2)`

square and square root cancel out:

`a=b^(2)`

Answer 2

Answer:
`a = b^2`

Reason:

Square both sides to undo the square root.

`√(a) = b\\\\\left(√(a)\right)^2 = b^2\\\\a = b^2\\\\`
