Answer:

$\sqrt[n]{x^a}=x^{a/n}$

Step-by-step explanation:

While the "law"

$\sqrt[n]{x^n}=x$

may seem more applicable, and may seem to be a special case of the law shown in the answer above, it is not true in general. For example, ...

$\sqrt{x^2}=|x|\ne x \quad\text{for x $$

A satellite launch rocket has a cylindrical fuel tank. The fuel tank can hold V cubic meters of fuel. If the tank measures d met

weqwewe [10]

Let the volume of the cylinder be V cubic meters, the diameter be d meters and the height be h meters.
Now we can write the formula for the volume as follows:
$V=\pi\frac{d^{2}}{4}h$
Rearranging the formula, the height becomes:
$\large h=\frac{4V}{\pi d^{2}}$

Solve the following, round the solution to the nearest tenth.<br> 57.7r + 23.23 =2.57

Ann [662]

57.7r + 23.23 =2.57

Subtract 23.23 from both sides:

57.7r = -20.66

Divide both sides by 57.7

r = -20.66 / 57.7

r = -0.358

round to nearest tenth = 0.4
