Choose the correct simplification of [tex]\left(7 x^3 y^3\right)^2[/tex].

A. [tex]49 x^6 y^6[/tex]

B. [tex]14 x^6 y^5[/tex]

C. [tex]49 x^5 y^5[/tex]

D. [tex]14 x^5 y^5[/tex]



Answer :

To simplify the expression [tex]\(\left(7 x^3 y^3\right)^2\)[/tex], we can follow these steps:

1. Apply the power rule for coefficients:

When raising a coefficient to an exponent, we raise the number to that power.

[tex]\[ 7^2 = 49 \][/tex]

2. Apply the power rule for each variable:

The power rule states that [tex]\((a^m)^n = a^{m \cdot n}\)[/tex]. We need to apply this for both [tex]\(x^3\)[/tex] and [tex]\(y^3\)[/tex].

For [tex]\(x\)[/tex]:
[tex]\[ (x^3)^2 = x^{3 \cdot 2} = x^6 \][/tex]

For [tex]\(y\)[/tex]:
[tex]\[ (y^3)^2 = y^{3 \cdot 2} = y^6 \][/tex]

3. Combine the simplified parts:

Now, combine the simplified coefficient and the variables:

[tex]\[ 49 \cdot x^6 \cdot y^6 \][/tex]

Therefore, the correct simplification of [tex]\(\left(7 x^3 y^3\right)^2\)[/tex] is:
[tex]\[ \boxed{49 x^6 y^6} \][/tex]

The correct answer from the given options is:
[tex]\[ 49 x^6 y^6 \][/tex]
