A. [tex]8^{\frac{8}{3}}[/tex]

B. [tex]8^{\frac{6}{3}}[/tex]

C. [tex]8^{\frac{6}{12}}[/tex]



Answer :

Sure! Let's simplify each of the given expressions step-by-step.

1. Simplify [tex]\(\left(8^{\frac{2}{3}}\right)^{4}\)[/tex]:
We use the power of a power property [tex]\((a^m)^n = a^{m \cdot n}\)[/tex].
[tex]\[ \left(8^{\frac{2}{3}}\right)^{4} = 8^{\frac{2}{3} \cdot 4} = 8^{\frac{8}{3}} \][/tex]
Therefore, [tex]\(\left(8^{\frac{2}{3}}\right)^4 = 8^{\frac{8}{3}}\approx 255.99999999999991\)[/tex].

2. Simplify [tex]\(8^{\frac{8}{3}}\)[/tex]:
[tex]\[ 8^{\frac{8}{3}}\approx 255.99999999999991 \][/tex]

3. Simplify [tex]\(8^{\frac{6}{3}}\)[/tex]:
We simplify the fraction [tex]\(\frac{6}{3}\)[/tex] first:
[tex]\[ 8^{\frac{6}{3}} = 8^{2} \][/tex]
And since [tex]\(8^2 = 64\)[/tex],
[tex]\[ 8^{\frac{6}{3}} = 64.0 \][/tex]

4. Simplify [tex]\(8^{\frac{6}{12}}\)[/tex]:
We simplify the fraction [tex]\(\frac{6}{12}\)[/tex]:
[tex]\[ 8^{\frac{6}{12}} = 8^{\frac{1}{2}} \][/tex]
This is the same as the square root of 8:
[tex]\[ 8^{\frac{1}{2}} = \sqrt{8} \][/tex]
And since [tex]\(\sqrt{8} = 2\sqrt{2}\)[/tex]:
[tex]\[ 2\sqrt{2} \approx 2.8284271247461903 \][/tex]

So, the simplified values are:
[tex]\[ \left(8^{\frac{2}{3}}\right)^{4} \approx 255.99999999999991, \quad 8^{\frac{8}{3}} \approx 255.99999999999991, \quad 8^{\frac{6}{3}} = 64.0, \quad 8^{\frac{6}{12}} \approx 2.8284271247461903 \][/tex]
