Rewrite the expression using only positive integer exponents.

Andrews [41]

Answer:

So we got:

$\left(m^{\frac{2}{3}}n^{\frac{-1}{3}}\right)^6$

$m^4\left(n^{\frac{-1}{3}}\right)^6\\$

More attention for $(n^{\frac{-1}{3}}\right))^6\\$

$n^{-2}$

$\frac{1}{n^2}$

Join:

$m^4\frac{1}{n^2}$

$\frac{1\cdot \:m^4}{n^2}\\\frac{m^4}{n^2}$

Therefore, the answer is $\frac{m^4}{n^2}$ , letter A

klio [65]

Answer:

18432 km/h

Step-by-step explanation:

It is given that a sound wave travels through iron at a rate of 5120 m/s.

We know that

1 km = 1000 m

1 hour = 60 minutes

1 minutes = 60 second

Using these conversions we get

1 m = 0.001 km

1 hour = 3600 second

$5120\text{ m/s }=5120\times 0.001\times 3600\text{ km/h}$

$5120\text{ m/s }=18432\text{ km/h}$

Therefore, the sound wave travels through iron at a rate of 18432 km/h.
