Answer:
C)√
72
Step-by-step explanation:
We will Simplify the radical by breaking the radicand up into a product of known factors.
When we do this, we figure out that...
A.√
49 = 7
B.√
64 = 8
D.√
121 = 11
BUT C) is different.
√
72 can not be divided into any whole number an exact amount of times.
So instead, this can be solved by writing it as shown:
Exact Form:
6
√
2
Decimal Form:
8.48528137
