Given the exponential equation 4x = 64, what is the logarithmic form of the equation in base 10?

zysi [14]

$4^{x} = 64$

By taking logarithmic of base 10

∴ $log 4^{x} = log 64$

∴ x log 4 = log 64

∴ $x = \frac{log \ 64}{log \ 4}$
note: we don't need to write the base in case of the base =10

∴ The correct choice is
x = log base 10 of 64, all over log base 10 of 4

Volume of a cylinder is $\pi r^2h$ , where r is the radius and h is the height.

This comes from the area of a circle being $\pi r^2$ . A cylinder is the area of the base circle multiplied by its height.

Using this formula, the volume of the given cylinder is
$\pi r^2(3r) \\
= 3 \pi r^3$
