Simplify 64^-1/3<br> A. -4<br> B. -1/4<br> C. 1/4<br> D. 4
shepuryov [24]

Remember, the numerator of an exponenent represents the root. As well, a negative exponent means to take the reciprocal of the positive exponent (a^{-b} = \frac{1}{a^{b}}.

So, 64^{-1/3} is equal to \sqrt[3]{64^{-1}} which is 1/4, because 1/4*1/4*1/4 is 1/64 (1/64 cubed root is 1/4).

For example, a^{b/c} = \sqrt[c]{b^{b}}

The answer is c.

Which algebraic expression is equivalent to the expression below?
prohojiy [21]
You can again ignore the parenthesis because you are not distributing anything. 
Your equation will look like this

3x + 11 + 6x

You can move each of these numbers around any way you like. You can combine the 3x and the 6x if you want, but they did not do that. You cannot take the x away and put it in front of the 11 though.

B. is your answer. All they did was move the 6x inside the parenthesis and the 11 out of the parenthesis. 

Always remember, when you are adding things together, the parenthesis don't matter!

A surface area of a cube is 96cm. What is the length of one side? What is its volume
Ganezh [65]
You are given the surface area of the cube which is 96cm2. You are asked to find the length of one side and its volume. Note that the surface area of the cube is equal to 6 times the square root of s (the side of the cube) and the volume is the cube root of s. So,  

SA = 6*s^2
96cm2 = 6*s^2
s^2 = 16cm
<u>s = 4cm, this is the length of one side.</u>  

V = s^3
V = (4)^3
<u>V = 64cm3, this is the volume of the cube.</u>
