How would you write the following expression as a sum or difference?

B

Step-by-step explanation:

Look at the expression inside the log( ).  Work from the outside in, so to speak.  First, there's a quotient (the cube root divided by 3x).

The cube root can be written using a rational exponent.

Use the exponent property to move the exponent 1/3 out.

This now matches answer choice B.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
