Answer 1

124

Explanation:

6+(249-2x)^(1/5) =7

above equation is in power form

transfer 6 on other side

(249-2x)^(1/5) = 7-6

(249-2x)^(1/5) =1

make both sides whole power 5 in order to get rid of 1/5 power

((249-2x)^(1/5))^5 = (1)^5

(249-2x) = 1

transfer 249 on other side

-2x =1-249

-2x=-248

2x=248

x=248/2

x=124
