Answer :

Sure! Let's simplify the expression [tex]\(\left(-3 x^{-2}\right)\left(4 x^4\right)\)[/tex] step-by-step.

1. Distribute the constants:
[tex]\[ \left(-3 x^{-2}\right) \left(4 x^4\right) \][/tex]
First, we can multiply the constants [tex]\(-3\)[/tex] and [tex]\(4\)[/tex]:
[tex]\[ -3 \cdot 4 = -12 \][/tex]

2. Combine the exponents of [tex]\(x\)[/tex]:
According to the property of exponents, [tex]\(a^m \cdot a^n = a^{m+n}\)[/tex], we can combine the terms with the variable [tex]\(x\)[/tex]:
[tex]\[ x^{-2} \cdot x^4 = x^{(-2 + 4)} \][/tex]

3. Add the exponents:
[tex]\[ -2 + 4 = 2 \][/tex]
So we have:
[tex]\[ x^{2} \][/tex]

4. Combine the results:
Now, multiply the constants and the variable part:
[tex]\[ -12 \cdot x^2 \][/tex]

Therefore, the simplified form of the expression [tex]\(\left(-3 x^{-2}\right)\left(4 x^4\right)\)[/tex] is:
[tex]\[ -12x^2 \][/tex]
