How do you simplify the expression \( \frac{w^5 \times w^4}{w^2} \)?

Back

Combine the exponents in the numerator: \( w^{5+4} = w^9 \), then subtract the exponent in the denominator: \( 9 - 2 = 7 \), so the answer is \( w^7 \).

What is the zero exponent rule?

Back

Any non-zero base raised to the power of zero equals one: \( a^0 = 1 \) (where \( a \neq 0 \)).
