Q. Select the equivalent expression.xy5x−6y−1x7x7y61x71x7y6
Simplify Exponents: Simplify the expression by dividing the exponents.When dividing powers with the same base, subtract the exponents.xy(5)x(−6)y(−1)=x(−6−1)y(−1−5)
Subtract Exponents: Perform the subtraction of exponents. x(−6−1)=x−7y(−1−5)=y−6 So, the expression becomes x−7y−6.
Convert Negative Exponents: Rewrite the expression with positive exponents.To convert a negative exponent to a positive exponent, take the reciprocal of the base.x−7y−6=(1/x7)(1/y6)=1/(x7y6)
Match Simplified Expression: Match the simplified expression with the given options.The simplified expression is x7y61, which matches the option x7y61.
