Evaluate $$\begin{aligned} \sqrt[3]{\sqrt{.000064}} \end{aligned}$$

Answer: Option B

Explanation:

$$\begin{aligned} => \sqrt{81} + \sqrt{0.81} = 10.09 - X \end{aligned}$$

$$\begin{aligned} => 9 + 0.9 = 10.09 - X \end{aligned}$$

$$\begin{aligned} => X = 10.09 - 9.9 = 0.19 \end{aligned}$$

Answer: Option B

Explanation:

$$\begin{aligned} = \sqrt[3]{\frac{512}{125}} \end{aligned}$$
$$\begin{aligned} = (\frac{8*8*8}{5*5*5})^{\frac{1}{3}} \end{aligned}$$

$$\begin{aligned} = \frac{8}{5} = 1\frac{3}{5} \end{aligned}$$

Answer: Option A

Answer: Option C

Explanation:

$$\begin{aligned} = \sqrt{\frac{25}{16}} \end{aligned}$$

$$\begin{aligned} = \frac{\sqrt{25}}{\sqrt{16}} \end{aligned}$$

$$\begin{aligned} = \frac{5}{4} \end{aligned}$$

$$\begin{aligned} = 1\frac{1}{4} \end{aligned}$$

Answer: Option C

Explanation:

21*21*21 = 9261
