Questions: Rewrite the expression with only positive exponents. Assume the variables do not equal zero.

Solution Steps

1. Calculate \(42^3\).
2. Rewrite the expression with only positive exponents.

To find \(42^3\), we perform the calculation: \[ 42^3 = 42 \times 42 \times 42 = 74088 \]

Given the expression \(x^{-2} \cdot y^{-3}\), we can rewrite it using only positive exponents. The negative exponents indicate that we can move the variables to the denominator: \[ x^{-2} \cdot y^{-3} = \frac{1}{x^2 \cdot y^3} \]
