Find the sum and then classify it.

[tex]\[
\frac{3}{4} + \sqrt{64}
\][/tex]

A. [tex]\(2.9580398 \ldots\)[/tex], irrational

B. [tex]\(8.0467384 \ldots\)[/tex], irrational

C. [tex]\(8.75\)[/tex], rational

D. [tex]\(64.75\)[/tex], rational



Answer :

Let's solve the problem step-by-step.

1. Evaluate the fraction:

[tex]\[ \frac{3}{4} \][/tex]

The value of this fraction is 0.75.

2. Evaluate the square root:

[tex]\[ \sqrt{64} \][/tex]

The square root of 64 is 8.0.

3. Calculate the sum:

[tex]\[ \frac{3}{4} + \sqrt{64} = 0.75 + 8.0 = 8.75 \][/tex]

4. Classify the sum:

A number is classified as rational if it can be expressed as the quotient of two integers (i.e., a fraction). The sum 8.75 can be written as the fraction [tex]\(\frac{35}{4}\)[/tex], which means it is a rational number.

Thus, the sum of [tex]\(\frac{3}{4} + \sqrt{64}\)[/tex] is 8.75, and it is a rational number.
