Question

simplify (7/2)^5x-5×(2/7)^x=343/8​

Answer 1

(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
