Step-by-step explanation:
To make this a bit easier to see, we'll expand that expression.
R to the 9th is just r times itself 9 times. R to the third is r times itself 3 times.
(excuse my bad formatting)
<u>The expression:</u>
<u>r • r • r • r • r • r • r • r • r • 1</u>
r • r • r • 1
Remember, anything and everything has a coefficient or denominator of 1.
So, we can cancel 3 r's from the numerator and denominator.
<u>r • r • r • r • r • r • 1</u>

That just equals .
Answer:
<em>The correct option will be: (b) 7 feet.</em>
Step-by-step explanation:
Suppose, the length of the garden is feet.
As the <u>shape of the garden is like a square, then the area of the garden</u> will be: feet²
Given that, the <u>area is 52 square feet</u>. So, the equation will be.......
So, the approximate length of the garden will be 7 feet.
