b.(7/5)^3
c.(-2)^3*(-5)^2

Answer 1

The Answer are as follows

Step-by-step explanation:

1. 36
2. $(7 \div 5) ^{3}$
3. $- 8 \times 25$

Answer 2

$a) 2^{2} \times 3^{3}$

$= 2\times 2 \times 3 \times 3 \times 3$

$= 4 \times 27$

$= 108$

$b) \Big( \frac{7}{5}\Big)^{3}$

$= \frac{7^{3}}{5^{3}}$

$= \frac{ 343}{125}$

$c) (-2)^{3} \times (-5)^{2}$

$= (-2)\times (- 2 )\times (-2) \times (-5) \times (-5)$

$= -8 \times 25$

$= - 200$
