Question

solve equation by using the square root . Express radicals in simpliest form
(3k-2)^2 = 16

Answer 1

Two get rid of a square (^) you sqrt both sides.. Any time you sqrt both sides you need to put +- on the side without the x.

So if you sqrt both sides.. you get 3k - 2 = +-4
You actually have two problems
3k -2 = 4 or 3x - 2 = -4
Then you solve each one by adding 2 and dividin by 3
3k = 6.... k = 3

3x = -2... k = -2/3

So k = -2/3 or 3

Answer 2

solution set is {-2/3,3}

Answer 3

Yes

Answer 4
