Answer:
<h2>The volume will be 549
in
hours.</h2>
Step-by-step explanation:
A mound of sand at a rock-crushing plant is growing over time means the volume will increase with passing time.
The relation between the time and the volume is given by , where t, time is in hours and v, volume is in .
We need to find the time, when the volume v will be = 549 .
Hence,
.

Answer:
Step-by-step explanation:
5^4 = 625. I hope your calculator will do this.
625 / 5 = 125
There is a more general way to do this which will be in harmony with the rest of the question.
5^4 / 5^1 = 5^(4 - 1) = 5^3 = 125
b^4 / b2 = b^(4 - 2) = b^2
a remains as it is at a^3
So the answer is 125 a^3 b^2
