We want to rewrite the given expression as a square of a monomial. We will get:
0.09*a^2 = (0.3*a)^2
So we have the expression:
0.09*a^2
We want to write this as a square of a monomial like:
(c*a)^2 = 0.09*a^2
Basically, we must find a number c such that:
c^2 = 0.09
c = √(0.09) = 0.3
Then the monomial is:
0.3*a
And we can rewrite the given expression as:
(0.3*a)^2
