Answer:
The simplest form is 1/r^7 + 1/s^12
Step-by-step explanation:
The given expression is r^-7+s^-12.
Notice that the exponents of both the base are negative
So, we will apply the rule which is:
a^-b = 1/a^b
Which means that to change the exponent into positive we will write it as a fraction:
r^-7+s^-12.
= 1/r^7 + 1/s^12..
Therefore the simplest form is 1/r^7 + 1/s^12....
Answer:
2 jars
Step-by-step explanation:
If one jar costs $2 and you have $4 then $2+$2=$4
8n-(2n-3)=12
8n-2n+3=12
6n=12-3
6n=9
n=9/6=3/2
