Advanced Math practice question

Answer: A. x²

(x²)³ = x⁶. Then x⁶/x⁴ = x⁶⁻⁴ = x².

Why the other answers are wrong

B. x⁵

x⁵ ADDS 2 and 3 for the power of a power (giving x⁵ before dividing... then x⁵/x⁴ = x); the exponents multiply: 2 × 3 = 6.

C. x

x comes from x⁵/x⁴, using 2 + 3 instead of 2 × 3.

D. x¹⁰

x¹⁰ adds the exponents 6 and 4 instead of subtracting.
