Rewrite negative exponent: We have the expression (w)/(y−4). To remove the negative exponent in the denominator, we can use the property of exponents that states a−n=1/(an). Therefore, y−4 can be rewritten as 1/(y4).
Multiply by reciprocal: Now, we can multiply the numerator by the reciprocal of the denominator to eliminate the denominator. This gives us w×(y4).
Simplify final expression: The expression is now simplified to w×y4, which is the same as w multiplied by y to the fourth power. This is the final answer, as there is no longer a denominator.
