The mass of a bar of chocolate is 1800g. the density of the chocolate is 9g/cm3 what is its volume?

Compare the overall density of the whole bar of chocolate to the density of 1/4 of the bar.  Was the density significantly different (if the difference is less than 0.2 g/cm3, then we should assume that it’s the same)?

Step-by-step explanation:

x = -2

y = 848

step-by-step explanation:

plug in the numbers

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
