Answer:
x = 11^(5/7)
Step-by-step explanation:
2x ^ 7/2 -22 = 0
Add 22 to each side
2x^ 7/5 -22+22 = 0+22
2x^7/5 =22
Divide by 2
2/2x^ 7/5 = 22/2
x^7/5 = 11
Take the 5/7th root on each side to get rid of the 7/5th power
x^ 7/5 ^ 5/7 = 11 ^ 5/7
x ^ (7/5*5/7) = 11^5/7
x = 11^(5/7)
This is the exact answer
