Select the correct answer.

What is the simplified form of [tex]$\pi \sqrt{3} - 8 \pi \sqrt{3}$[/tex]?

A. [tex]$-7 \sqrt{3} \pi$[/tex]
B. [tex][tex]$-9 \sqrt{3} \pi$[/tex][/tex]
C. [tex]$-7 \pi$[/tex]
D. [tex]$-9 \pi$[/tex]



Answer :

Let's simplify the expression [tex]\(\pi \sqrt{3} - 8 \pi \sqrt{3}\)[/tex] step by step.

1. Identify Like Terms: Notice that both terms involve [tex]\(\pi \sqrt{3}\)[/tex].

2. Factor Out the Common Factor: To simplify, we can factor out [tex]\(\pi \sqrt{3}\)[/tex] from both terms.
[tex]\[ \pi \sqrt{3} - 8 \pi \sqrt{3} = (\pi \sqrt{3})(1) - (\pi \sqrt{3})(8) \][/tex]

3. Combine Like Terms: Now combine the like terms by subtracting the coefficients.
[tex]\[ (\pi \sqrt{3})(1 - 8) = (\pi \sqrt{3})(-7) \][/tex]

4. Simplified Expression:
[tex]\[ -7 \pi \sqrt{3} \][/tex]

Having simplified the expression, we see that [tex]\(-7 \pi \sqrt{3}\)[/tex] matches one of the given options.

Now, let's match our result with the options given:
A. [tex]\( -7 \sqrt{3} \pi \)[/tex]
B. [tex]\( -9 \sqrt{3} \pi \)[/tex]
C. [tex]\( -7 \pi \)[/tex]
D. [tex]\( -9 \pi \)[/tex]

Clearly, the simplified form of [tex]\(\pi \sqrt{3} - 8 \pi \sqrt{3}\)[/tex] is [tex]\( -7 \pi \sqrt{3}\)[/tex], which corresponds to option A.

Therefore, the correct answer is:
- A. [tex]\( -7 \sqrt{3} \pi \)[/tex]
