Answer 2

Answer:

Step-by-step explanation:

(a). $\frac{2^4}{3^4}$ × $\frac{3^2}{2^4}$ = $\frac{1}{3^2}$ = 1/9

(b). $\frac{2^3}{3^3}$ × $\frac{3^4}{5^4}$ × $\frac{7^3}{2^3}$ = $\frac{1029}{625}$

(c). $-\frac{1}{3^5}$ × $\frac{3^3}{1}$ × $\frac{3^2}{4^2}$ =  $-\frac{1}{4^2}$ = - 1/16

(d). $\frac{3^3}{2^6}$ × $\frac{2^3}{5^3}$ × $\frac{1}{2^3}$ = $\frac{3^3}{2^6*5^3}$ = $\frac{27}{8000}$ = 0.003375
