Question

please tell me the answer​

Answer 1

Answer:

${5}^{2} \times {5}^{4} = {5}^{2 + 4} = {5}^{6} \\ {5}^{8} \div {5}^{3} = {5}^{8 - 3} = {5}^{5} \\ ({3}^{ {2})^{3} } = {3}^{2 \times 3} = {3}^{6} \\ { (\frac{11}{12}) }^{3} = \frac{ {11}^{3} }{ {12}^{3} }$

Answer 2

Answer:

1) 15625

2) 3125

3) 243

4) 0.770

Step-by-step explanation:

1) 5² X 5⁴ = 25 X 625

= 15625

2) 5⁸ ÷ 5³ = 5⁵

we minus the powers during the divide sign so 8-3 = 5

= 3125

3) (3²)³ = 3²+³ = 3⁵ (during multi we add the powers)

= 243

4) (11/12)³

= 11³/12³ = 1331/1728

= 0.770
