Question

Directions - Simplify the expression so all exponents are positive. \(b^5 x^{-9} y^7 = ______\). a) \(b^5 x^9 y^7\) b) \(b^5 x^{-7} y^9\) c) \(b^9 x^5 y^7\) d) \(b^5 x^{-9} y^{-7}\)

Answer 1

The expression is simplified to have positive exponents as (b⁵ y⁷) / x⁹

How to simplify the expression

To simplify the expression b⁵ x⁻⁹ y⁷ so that all exponents are positive, we can move the terms with negative exponents to the denominator and change the signs of the exponents

This is done to result to

b⁵ x⁻⁹ y⁷ = (b⁵ y⁷) / x⁹
