Answer 4

@Jhannybean

Answer 5

u need to find the square root of 196

Answer 6

That's part of it, \[\sqrt{196} = \sqrt{4 \cdot 7 \cdot 7}\]Now remember, for every TWO numbers inside the square root, 1 of them can come out of the square root. SO... \[\sqrt{196} = \sqrt{\color{red}{2 \cdot 2} \cdot \color{green}{7 \cdot 7}}\] That means 1 \(\color{red}{2}\) comes out and 1 \(\color{green}{7}\) comes out. Multiply these together, what do you get?

Answer 7

Not quite. How did you arrive at that conclusion?

Answer 8

Your initial guess was right, but I want you to tell me how you found it.

Answer 9

it was a guess

Answer 10

I'm confused @Jhannybean

Answer 11

Which part are you confused with? I will guide you from there.

Answer 12

lets start over

Answer 13

If it helps in any way... let's try a different approach. If you don't like this method either, ignore it. \[(196)^{1/2} = (4)^{1/2} \cdot (49)^{1/2}\] What does.... \[4^{1/2}=~?\]\[(49)
^{1/2} =~?\]
