Question

Evaluate the following expression, or state that the root is not a real number.

square root 64+36

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A. The root is a real number and 64 + 36 = blank

B. The root is not a real number.

Answer 1

To evaluate the expression \(\sqrt{64 + 36}\), we first calculate the sum inside the square root:

\[
64 + 36 = 100
\]

Now we can find the square root:

\[
\sqrt{100} = 10
\]

So, the root is a real number.

The correct choice is:

A. The root is a real number and \(64 + 36 = 100\).
