This is the first part of a three-part problem. express $18\sqrt 8$ in the form $a\sqrt b$, where $a$ and $b$ are integers and $b$ is as small as possible.

Where a=36 and b=2 with b is small.

Step-by-step explanation:

Given problem

We have to write the given problem in form of , where a and b are integers and b is as small as possible.

Consider the given problem

8 can be written in factored form as 2 × 2 × 2

Substitute, in given problem, we have

This can be written as,

We know , thus,

Thus,

Where a=36 and b=2 with b is small.

just sum

10 + 10 = 20
