If \(x\neq 0\), what is the simplified form of \(\frac{(x^2)^3\cdot x^{-1}}{x^2}\)?

Answer and explanation

Correct answer: \(x^3\)

Using the laws of exponents, \((x^2)^3=x^6\). Hence, \(\frac{x^6\cdot x^{-1}}{x^2}=x^{6-1-2}=x^3\). Therefore, option A is correct. Option B results from not correctly subtracting the exponent of the denominator. Exam tip: add exponents when multiplying powers with the same base and subtract them when dividing.
