Answer:

Step-by-step explanation:

Part A.

Expression $(100)^{\frac{1}{2}}$ = 10

Because 100 = $(10)^{2}$ and $[(10)^2]^{\frac{1}{2}}=10^1=10$

[Since, $(a^{2})^{\frac{1}{2}}=a^{2\times \frac{1}{2}}=a^1$ ]

Part B.

When simplified, the answer is RATIONAL.

[Since, 10 can be written as $\frac{10}{1}$ ]
