Question

solve the equation. check your solution. 4=sqrt(h)-6

Answer 1

\[4=\sqrt{h}-6\]

Answer 2

Do you know the first step, hun?

Answer 3

no, I looked at the book but I am completely lost, I cant follow their steps. I was thinking you need to add 6 to both sides first making it \[10=\sqrt{h}\] am I right?

Answer 4

Yes. Go on.

Answer 5

then you solve for sqrt to get h?

Answer 6

There is no sqrt of H, since it's not h^2. So you perform the opposite action of a square root.

Answer 7

don't understand the opposite action, think this is where I get lost

Answer 8

h = 100, by the way.

Answer 9

Want me to explain it to you?

Answer 10

please in English not math, lol

Answer 11

Alright. One second. Let me type something up to help you understand.

Answer 12

k

Answer 13

So we have the square root in the middle. How we undo that is by squaring both sides. So if we square both sides to get the x out, we also square the 10, which gives us 100. Make sense?

Answer 14

so squaring 10 is 3.16, and h is 100

Answer 15

wait that is not right is it?

Answer 16

ow wait, square of h = 100, and if we take 10*10 that also =100

Answer 17

lightbulb just went off.....squaring is opposite of square root!!!!!

Answer 18

\[10 = \sqrt{h}\rightarrow 10^2 = \sqrt{h^2}\]

Okay, so we know that if we have 2 terms under the square root symbol we can remov ethem. \[10^2 = \sqrt{h^2} = 100 = h\]

Answer 19

CORRECT!

Answer 20

\[4=\sqrt{100}-6\]

Answer 21

So the same thing.

10 = sqrt{100}

Now square both numbers
100 = 10,000

Which is false.

Answer 22

ok, I see what you are saying....got it...I am going to write these steps down for the next problems, thanks and I appreciate your patience!!!!

Answer 23

No problem. Remember to give me a medal !!
