Question

Make x the subject of the formula
y=a √x

Answer 1

Y^2/a = x

Explanation:

Y = a sqr X

Square both sides

Y^2 = a * x

Divide a

Y^2/a = x

Answer 2

`x = (y^2)/(a^2)`

Explanation:

`y = a√(x)`

Square both sides.

`(y)^2 = (a√(x))^2`

`y^2 = a^2(√(x))^2`

`y^2 = a^2x`

Divide both sides by a².

`(y^2)/(a^2) = x`

Switch sides.

`x = (y^2)/(a^2)`
