[tex]\boxed{\ }[/tex]


Sagot :

Absolutely, let's solve the given expression step by step.

We need to evaluate the expression:
[tex]\[ \frac{7^2}{x^2 - 2} \][/tex]
for [tex]\(x = 3\)[/tex].

Step 1: Calculate [tex]\(7^2\)[/tex]

First, let's handle the numerator:
[tex]\[ 7^2 = 49 \][/tex]

Step 2: Calculate [tex]\(x^2 - 2\)[/tex]

Now, for the denominator, substitute [tex]\(x = 3\)[/tex] into [tex]\(x^2 - 2\)[/tex]:
[tex]\[ 3^2 - 2 = 9 - 2 = 7 \][/tex]

Step 3: Divide the Numerator by the Denominator

Finally, divide the numerator by the denominator:
[tex]\[ \frac{49}{7} = 7 \][/tex]

The value of the expression [tex]\(\frac{7^2}{x^2 - 2}\)[/tex] for [tex]\(x = 3\)[/tex] is [tex]\(\boxed{7}\)[/tex].
