Answer:

20cm

Step-by-step explanation:

Let s = the length of the base

Let 4s = the length of the height

V = BH Since the base is a square, B = s2

V = s2 H

500 = s2(4s)

125 = s3

s = 5 cm

4s = 20 cm - the height

Irrational equations 64^1/3 how to simplify?

balandron [24]

For indicies, the numerator is the normal power, and the denominator is a root as such. So 1/2 would be square root, 1/3 would be cube root, 1/4 would be 4th root and so on.

So, 64^(1/3) is the third root of 64, which is equal to 4.

Suppose we want to choose 7 colors, without replacement, from 9 distinct colors

Digiron [165]

The number of ways to choose the colors is 36

<h3>How to determine the number of ways?</h3>

The given parameters are:

Colors = 9

Colors to choose = 7

Since order does not matter, then it is combination

This is calculated using:

$^nC_r = \frac{n!}{(n - r)!r!}$

This gives

$^nC_r = \frac{9!}{7!2!}$

Evaluate

$^nC_r = 36$

Hence, the number of ways is 36
