Remember
∛(mn)=(∛m)(∛n)
and
if you have the 3rd root of a negative number, the root will be negative

∛-216=(∛216)(∛-1)
we know that 216=6^3 (you know, just fun fact)
6(∛-1)
3rd root of -1 is -1 ((-1)^3=-1)
6(-1)
-6

Find the percent of change. Round to the nearest percent.

katovenus [111]

Answer:

Step-by-step explanation:

You will have to use this formula

$\frac{new value-oldvalue}{oldvalue}$

When substituted in you have $\frac{30-66}{66}$

30-66=-36

-36/66= -0.54 (54 repeating)

Then you have to convert this into a percentage, -54.54(repeating) percent

To the nearest hundredth you would round down to<u> -54.5%</u>.

It is a Decrease because it is negatated.

Simplify 2 to the 5 power to the fourth power over 3 to the second power

melisa1 [442]

I'm assuming you mean 2^(5)(4/3)(2).
So multiplying all of the powers together yields 2^(40/3)
