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.
