Question

$$( \frac { 5 } { 7 } ) ^ { - 2 } \times ( \frac { 15 } { 49 } ) ^ { - 3 }$$

$\frac{5764801}{84375}\approx 68.323567407$

Calculate $\frac{5}{7}$ to the power of $-2$ and get $\frac{49}{25}$.

$$\frac{49}{25}\times \left(\frac{15}{49}\right)^{-3}$$

Calculate $\frac{15}{49}$ to the power of $-3$ and get $\frac{117649}{3375}$.

$$\frac{49}{25}\times \frac{117649}{3375}$$

Multiply $\frac{49}{25}$ and $\frac{117649}{3375}$ to get $\frac{5764801}{84375}$.

$$\frac{5764801}{84375}$$

$\frac{7 ^ {8}}{3 ^ {3} \cdot 5 ^ {5}} = 68\frac{27301}{84375} = 68.32356740740741$
