Answer:
Monomial
is a square of monomial 
Step-by-step explanation:
Given monomial 
Using property
note that

So,

Now use property
to rewrite the previous expression:

Hence, monomial
is a square of monomial 
4900=4200(1+r/2)^(2*4)
Solve for r
R=(4900/4200)^(1/8))-1)*2
R=((4,900÷4,200)^(1÷8)−1)×2
R=0.039*100=3.9%
5 times 10^7= 50000000
6 times 10^4= 60000
