Simplify [tex]\left(m^6 n\right)^3[/tex].

A. [tex]m n^{21}[/tex]

B. [tex]m^9 n^3[/tex]

C. [tex]m^{18} n[/tex]

D. [tex]m^{18} n^3[/tex]



Answer :

To simplify the expression [tex]\(\left(m^6 n\right)^3\)[/tex], we need to apply the properties of exponents systematically.

1. Identify the components inside the parentheses:
[tex]\(\left(m^6 n\right)\)[/tex].

2. Apply the exponent to each term inside the parentheses:
The expression inside the parentheses is [tex]\(m^6\)[/tex] and [tex]\(n\)[/tex].

3. Use the power of a product property [tex]\((ab)^c = a^c \cdot b^c\)[/tex]:
[tex]\(\left(m^6 n\right)^3 = (m^6)^3 \cdot (n)^3\)[/tex].

4. Simplify each part separately using the power of a power property [tex]\((a^b)^c = a^{b \cdot c}\)[/tex]:
[tex]\[ (m^6)^3 = m^{6 \cdot 3} = m^{18} \][/tex]
[tex]\[ (n)^3 = n^3 \][/tex]

5. Combine the simplified parts:
[tex]\[ m^{18} \cdot n^3 \][/tex]

So, the simplified expression for [tex]\(\left(m^6 n\right)^3\)[/tex] is:

[tex]\[ m^{18} n^3 \][/tex]

Hence, the correct answer is [tex]\(m^{18} n^3\)[/tex].
