Answer:
Exfoliation
Step-by-step explanation:
Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.
Rocky desert landscapes are particularly vulnerable to thermal stress. The outer layer of desert rocks undergo repeated stress as the temperature changes from day to night. Eventually, outer layers flake off in thin sheets, a process called exfoliation.
10m15n10 because you just multiply everything by 5
It is right but what's the full question
By the power rule,
(this seems to be the step you're not getting?)
The next step is to pull out a common factor of 
from the antiderivative:
so that the final result is
