Question

Can someone please explain in detail how to solve radical equations? (1, 2, &10)

Answer 1

Step-by-step explanation:

- First, the radical needs to be alone on one side of the equation, if there is - 4, - 3 next to it then you'll have to transfer it to the opposite side like that:

5. (y+7)^0.5 - 4=4

(y+7)^0.5=8......

- Second, you need to square the two sides of the equation :

5.((y+7)^0.5) ^2=8^2

Y+7=64

Y+7-7=64-7

Y=57

Note: if the radical's index is (2) then you'll square the two sides of the equation, but if the index is (3) you'll have to cube the two sides of the equation, "look at the exercises 9,10"
