(96+92+80+91+86+x)= 90
________________
6
(445+x)=90
_____
6
then you multiply 6 on both sides
445+×=540
-445. -445
x= 95

Answer:
x^(1/6)
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
__
Here, we have a=X, b=1/2, c=1/3, so the quotient is ...
(X^(1/2))/(X^(1/3)) = X^(1/2 -1/3) = X^(1/6)
_____
Expressed as a radical, this is ...
