Q. Select the equivalent expression.(s7s−8)61s515s25s21s5
Simplify Exponents: Simplify the expression inside the parentheses by using the laws of exponents.When dividing powers with the same base, subtract the exponents.(s(−8))/(s(7))=s(−8−7)=s(−15)
Apply Exponent Rule: Apply the exponent outside the parentheses to the simplified base.(s−15)61=s−15×61=s−615=s−25
Convert to Positive Exponent: Convert the negative exponent to a positive exponent by taking the reciprocal of the base.s(−25)=s(25)1
Rewrite with Radical: Rewrite the expression with a radical to represent the fractional exponent.s251=s51
Compare with Options: Compare the result with the given options. The equivalent expression is s51.
