Option 1 is the correct answer. The open circle means that the end value (78) is not included in the solution. That is why the inequality statement says 78 > x.

In Exercise, evaluate each expression.<br> 643/4
Goshia [24]

Answer:

\\ 64^{\frac{3}{4}} = 16\sqrt{2}

Step-by-step explanation:

We need here to remember that:

\\{(x^{a})}^{b} = x^{a * b}

\\{x^{a} * x^{b} = x^{a + b}

Then,

\\ 64^{\frac{3}{4}} = {(8^{2})}^{(\frac{3}{4})} = {{(2^{3})}^{2}}^\frac{3}{4}

\\ 64^{\frac{3}{4}} = {{2^{3}}^2}^\frac{3}{4} = 2^\frac{3*2*3}{4}

\\ 64^{\frac{3}{4}} = 2^\frac{2*3*3}{4} = 2^\frac{3*3}{2} = 2^\frac{9}{2}

\\ 64^{\frac{3}{4}} = 2^{\frac{9}{2}}

Since \\ \frac{9}{2} = \frac{4}{2} + \frac{4}{2} + \frac{1}{2}

\\ 64^{\frac{3}{4}} = 2^{\frac{9}{2}} = {2^{(\frac{4}{2} + \frac{4}{2} + \frac{1}{2})}

\\ 64^{\frac{3}{4}} = 2^{\frac{4}{2}} * 2^{\frac{4}{2}} * {2}^{\frac{1}{2}

\\ 64^{\frac{3}{4}} = 2^{2} * 2^{2} * {2}^{\frac{1}{2}

\\ 64^{\frac{3}{4}} = 4 * 4 * \sqrt{2} = 16 \sqrt{2}
