What will come in the place of the question mark $(?)$ in the following equation?
$(0.64)^{4} \div (0.512)^{3} \times (0.8)^{4} = (0.8)^{?+3}$

What value will come in place of the question mark (?) in the following question? (You are not expected to calculate the exact value)
$10^{3} \times 100^{3} + 999999999 = 10^{?} + 10^{?}$

On simplification of $\frac{(2.644)^{2}-(2.356)^{2}}{0.288},$ we get

The value of $\frac{2.75 \times 2.75 \times 2.75 - 2.25 \times 2.25 \times 2.25}{2.75 \times 2.75 + 2.75 \times 2.25 + 2.25 \times 2.25}$ is:

If the cube root of $79507$ is $43$,then the value of $\sqrt[3]{79.507} + \sqrt[3]{0.079507} + \sqrt[3]{0.000079507}$ is

The value of $\frac{2^{1 / 2} \cdot 3^{1 / 3} \cdot 4^{1 / 4}}{10^{-1 / 5} \cdot 5^{3 / 5}} \div \frac{3^{4 / 3} \cdot 5^{-7 / 5}}{4^{-3 / 5} \cdot 6}$ is
