Solve the equation for x.
15 = -2x + 3

The answer is -6 because, u will transfer 3 to the other side where 15 is ,so the answer will be 12. Divide 12 by -2 it will be -6.

The correct answer is last option 1/x²⁴

Step-by-step explanation:

Points to remember

1).  (x)⁻ᵃ = 1/xᵃ

2).  (xᵃ)ᵇ = xᵃᵇ

3).  xᵃ/xᵇ = xᵃ⁻ᵇ

It is given that, { x⁻⁶/x² }³

To find the equivalent expression

{ x⁻⁶/x² }³ = (x⁻⁶ ⁻ ²)³

 = (x⁻⁸)³

 = x⁻²⁴

 = 1/x²⁴

Therefore the correct answer is last option

{ x⁻⁶/x² }³  = 1/x²⁴
