Simplify the expression:

[tex]\[ \frac{3}{a^{-2}} \][/tex]


Sagot :

Sure, let's simplify the expression [tex]\(\frac{3}{a^{-2}}\)[/tex] step by step.

1. Understand the given expression:
[tex]\(\frac{3}{a^{-2}}\)[/tex]

2. Recall the property of exponents:
The negative exponent rule states that [tex]\(a^{-n} = \frac{1}{a^n}\)[/tex]. Hence, [tex]\(a^{-2} = \frac{1}{a^2}\)[/tex].

3. Substitute the expression [tex]\(a^{-2}\)[/tex] with [tex]\(\frac{1}{a^2}\)[/tex]:
[tex]\[ \frac{3}{a^{-2}} = \frac{3}{\frac{1}{a^2}} \][/tex]

4. Simplify the fraction:
Dividing by a fraction is equivalent to multiplying by its reciprocal. So, we have:
[tex]\[ \frac{3}{\frac{1}{a^2}} = 3 \times a^2 \][/tex]

5. Result:
[tex]\[ 3 \times a^2 = 3a^2 \][/tex]

Thus, the simplified form of [tex]\(\frac{3}{a^{-2}}\)[/tex] is [tex]\(3a^2\)[/tex].
