Simplify the expression open paren the fraction with numerator 1 and denominator 4 A b close paren to the negative 2 power Assume A is not equal to 0 , b is not equal to 0
A
the fraction with numerator A squared b squared and denominator 4B
negative the fraction with numerator 1 and denominator 16 A squared b squaredC
negative 16 A squared b squaredA negative exponent means take the reciprocal, then apply the exponent: (1/(4Ab))^-2 = (4Ab)^2. Squaring each factor gives 4²A²b² = 16A²b², so the correct choice is 16 A squared b squared.
