Question

Simplify(5/9)-2×(5/3)2÷(1/5)-2in exponential form with negative exponent.

Answer 1

$( \frac{5}{9} )^{ - 2} \times ( \frac{5}{3} )^{2} \div ( \frac{1}{5} )^{ - 2} \\ = ( \frac{9}{5} ) ^{2} \times ( \frac{5}{3} )^{2} \div ( \frac{5}{1} )^{ 2} \\ = \frac{9}{5} \times \frac{9}{5} \times \frac{5}{3} \times \frac{5}{3} \times \frac{1}{5} \times \frac{1}{5} \\ = \frac{9}{25} \\ = ( \frac{3}{5} ) ^{2} \\ = (\frac{5}{3} )^{ - 2}$
