Final: Three Rules, One Line

When an expression uses several exponent rules, work from the inside out. First simplify the power of a power by multiplying the exponents. Then multiply the powers with the same base by adding their exponents. Then divide by subtracting the exponents.

For (x^2)^3 × x ÷ x^4: the power of a power gives (x^2)^3 = x^6. The product gives x^6 × x = x^7, because x on its own has exponent 1. The quotient gives x^7 ÷ x^4 = x^3.
