Question

Solve (4x - 11)^1/2 = 3


x = 5
x = 3
x = 2
None of the above

Answer 1

i suggest squaring both sides first, that way you get rid of that ^1/2

Answer 2

you should get: 4x-11=9
Then add 11 to both sides: 4x=20
Finally divide both sides by 4 and get: x=5

Answer 3

Thank you! (:

Answer 4

x=5

Answer 5

the reciprocal of the first equation the square it that how you will get rid of the 1/2
