Hello!
The variable "n" represents an exponent.
An exponent is used to multiply a number (b) by itself "n" times. For example, if the expression were to read (b²) it would represent the following:
b × b
The same could be said for (b³):
b × b × b
Even (

):
b × b × b × b × b × b × b × b × b × b
I hope this helps!

Answer is D... the -3 outside the absolute/parenthesis shifts is down
Answer:
z = 
Step-by-step explanation:
Given z is directly proportional to x and inversely proportional to y then the equation relating them is
z =
← k is the constant of proportionality
To find k use the condition x = 7, y = 7 and z = 2
k =
=
= 2
z =
← equation of proportionality
When x = 10 and y = 12, then
z =
=
=
