1/2 rational exponent represents a square root.
Therefore, option A is correct.
Step-by-step explanation:
As we know that raising to the one-half power i.e.
is the same
as taking the square root.
- so
is the same as the square root of
.
For example, taking the square root of 4 will determine:





so the expression becomes


∵ 
so, 1/2 rational exponent represents a square root.
Therefore, option A is correct.
To do this, we have to multiply the 7 feet diameter by pi to get the circumference because the formula for circumference is

, or circumference = pi times diameter. 7 x 3.14 (pi rounded) = 21.98
