Q. The expression (m31m2)−21 is equivalent to(1) 16m5(3) −m5m(2) 6m51(4) m3m1
Simplify inside parentheses: We start by simplifying the expression inside the parentheses before dealing with the outer negative exponent.The expression inside the parentheses is a quotient of powers with the same base, so we can subtract the exponents.m31m2=m2−31=m36−31=m35
Apply negative exponent: Now we apply the outer exponent of −21 to the simplified base.(m35)−21=m(35⋅−21)=m−65
Reciprocal of base: The negative exponent indicates that the expression is the reciprocal of the base with the positive exponent. m−65=m651
Rewrite as radical expression: The expression m651 can be rewritten as a radical expression.m651=6m51
Compare with options: We compare the simplified expression with the given options.The correct option that matches our simplified expression is option (2)(6m51).
