- When you are raising a number to a negative power, it is the same as dividing 1 by that power when it is positive. So, can be written as: .

is 125, so we can substitute that in to get:

- This expression is the same as the one before, but it is negative. This means we can say

- We can start by writing as . Now, we can distribute the exponent -1, and simplify. Remember when raising a power in parenthesis to another power, you multiply them:

- We can start by writing as . Now, we can distribute the exponent 0, and simplify:

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.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
