If you mean something like 4^3 * 4^14 you have to obey two rules.

1. The base number must be the same for both numbers making up the product.

2. The powers must be added.

In this case 1 and 2 both can be obeyed.

4^3 * 4^14 = 4^(3 + 14) = 4^17

What is the exact circumference of the circle? Circle A with diameter 60 feet. 10π feet 20π feet 40π feet 60π feet

Gelneren [198K]

The circumference of a circle is 2•3.14(Pi)•R(radius) or 3.14(Pi)•D(diamater).
Since we have our diameter, 60, we need to multiply it by Pi.
60Pi is your answer.

I hope this helps!

Please help me :)) algebra 2! what are the real roots?

irina1246 [14]

Answer:

Step-by-step explanation:

So we have the equation:

$3(x-4)^\frac{4}{3}+16=64$

First, let's subtract 16 from both sides:

$3(x-4)^\frac{4}{3}=48$

Now, let's divide both sides by 3:

$(x-4)^\frac{4}{3}=16$

Remember that with fractional exponents, we can move the denominator into the root position. Therefore:

$(\sqrt[3]{x-4})^4=16$

Let's take the fourth root of both sides. Since we're taking an even root, make sure to have the plus-minus symbol!

$\sqrt[3]{x-4} =\pm 2$

Cube both sides. Since we're cubing, the plus-minus stays.

$x-4=\pm 8$

Add 4 to both sides.

$x=\pm 8+4$

Calculator:

$x=8+4\text{ or } x=-8+4\\x=12\text{ or } x=-4$

So, our answer is A.

And we're done!
