A. [tex]\frac{g^{15}}{8 h^6}[/tex]

B. [tex]\frac{g^5}{2 h^2}[/tex]

C. [tex]\frac{g^{15}}{2 h^6}[/tex]

D. [tex]\frac{g^8}{8 h^5}[/tex]



Answer :

To determine which expression is equivalent to \(\frac{(2g^5)^3}{(4h^2)^3}\), we need to simplify the given expression step-by-step.

First, let's simplify the numerator \((2g^5)^3\):
[tex]\[ (2g^5)^3 = 2^3 \cdot (g^5)^3 \][/tex]
Calculate each part separately:
[tex]\[ 2^3 = 8 \][/tex]
[tex]\[ (g^5)^3 = g^{5 \cdot 3} = g^{15} \][/tex]
So the numerator becomes:
[tex]\[ 8g^{15} \][/tex]

Next, let's simplify the denominator \((4h^2)^3\):
[tex]\[ (4h^2)^3 = 4^3 \cdot (h^2)^3 \][/tex]
Calculate each part separately:
[tex]\[ 4^3 = 64 \][/tex]
[tex]\[ (h^2)^3 = h^{2 \cdot 3} = h^6 \][/tex]
So the denominator becomes:
[tex]\[ 64h^6 \][/tex]

Now, our expression looks like this:
[tex]\[ \frac{8g^{15}}{64h^6} \][/tex]

We can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 8:
[tex]\[ \frac{8g^{15}}{64h^6} = \frac{8 \cdot g^{15}}{8 \cdot 8h^6} = \frac{g^{15}}{8h^6} \][/tex]

Thus, the simplified form of the given expression is:
[tex]\[ \frac{g^{15}}{8h^6} \][/tex]

Therefore, the correct answer is:
[tex]\[ \boxed{\frac{g^{15}}{8h^6}} \][/tex]
