Question

simplify each of the following and express each as a rational number
(a)(2/3)^3×(3/5)^4× (7/2)^3
(b)(-1/3)^5× 3^3 ×( 3/4)^2​

Answer 1

${( \frac{2}{3} )}^{ 3} \times {( \frac{3}{5}) }^{4} \times { (\frac{7}{2}) }^{3}$

$= \frac{8}{27} \times \frac{81}{625} \times \frac{343}{8}$

$= \frac{1029}{625}$

${ (\frac{ - 1}{3} )}^{5} \times {3}^{3} \times {( \frac{3}{4} )}^{2}$

$= - \frac{1}{243} \times 27 \times \frac{9}{16}$

$= - \frac{1}{16}$
