Verified answer
(7/2)^5x-5(2/7)^x=343/8
We move all terms to the left:
(7/2)^5x-5(2/7)^x-(343/8)=0
Domain of the equation: 2)^5x!=0
x!=0/1
x!=0
x∈R
Domain of the equation: 7)^x!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
(+7/2)^5x-5(+2/7)^x-(+343/8)=0
We get rid of parentheses
(+7/2)^5x-5(+2/7)^x-343/8=0
We calculate fractions
We do not support expression: x^5
