Question

Good evening everyone?please answer my question below.PLEASE

3 x 3 in the power of minus 3

5 in the power of 7 x 5 in the power of minus 3

8 in the power of minus 3 x 8 in the power of 3

Answer 1

Answer:

$\frac{1}{ {3}^{2} } = \frac{1}{9}$

${5}^{4} = 625$

${8}^{3 - 3} = {8}^{0} = 1$

Step-by-step explanation:

$3 \times {3}^{ - 3} = 3 \times \frac{1}{ {3}^{ 3} } = 3 \times \frac{1}{27} = \frac{1}{9}$

${5}^{7} \times {5}^{ - 3} = {5}^{7} \times \frac{1}{ {5}^{3} } = \frac{ {5}^{7} }{ {5}^{3} } = {5}^{7 - 3} = {5}^{4} = 625$

${8}^{ - 3} \times {8}^{3} = \frac{1}{ {8}^{3} } \times {8}^{3} = 1$

HOPE IT'LL HELP..
