Question

is anybody good at simplifying square roots because I need help

Answer 1

sure.
what's your question?

Answer 2

how do I simplify this

Answer 3

are you still there and can you draw it out but if you cant please use numbers

Answer 4

you can't find a square root of a negative so first you make it not a negative by simply taking away the negative. so to find a sqrt of a number look at the numbers at the bottom and basicly multiply it by itself so that is why it's called a square root. basicly the answer is 13

Answer 5

okay thanks the next one is

Answer 6

does it have the varuable's value? for example: x=5?

Answer 7

ummm are you there still :(

Answer 8

no

Answer 9

ok.
what are the answers they give you, if any?

Answer 10

none it is unkown

Answer 11

I just have to simplify them

Answer 12

@JuliusTheGreat

Answer 13

lol im not good at moth hun sorry

Answer 14

@PinkSapphire

Answer 15

can you help me

Answer 16

I haven't learned this yet :(

Answer 17

ohhh sorry then

Answer 18

@tkhunny can you please help me

Answer 19

They are ALL the same. Find a "Prime" factorization and identify all perfect squares.

\(-\sqrt{169} = -\sqrt{13^{2}} = -13\)

\(\sqrt{(x+3)^{2}} = |x+3|\). The absolute values are necessary, since we don't know enough about (x+3). If we KNOW \(x+3 \ge 0,\;then\;\sqrt{(x+3)^{2}} = x+3\). On the other hand, if we KNOW \(x+3<0,\;then \sqrt{(x+3)^{2}} = -(x+3)\)

This was not a problem with \(\sqrt{169}\), since we KNOW \(13 > 0\).

Answer 20

@tkhunny I don't noe how to do that when it has a variable at the end of it

Answer 21

What of my explanation proved inadequate? It makes no difference at all with variables or numbers or cats or Terracotta Soldiers. Find a "Prime Factorization" and exploit all perfect squares.

Please demonstrate another example. You do the work.

Answer 22

\(\sqrt{25y} = \sqrt{5^2\cdot y} = \sqrt{5^{2}}\cdot \sqrt{y} = 5\sqrt{y}\)

There are not perfect squares related to 'y', so just leave it in there.

Show another one. This time, show your work. "I got this..." is NOT a sufficient response. What are you doing? What are you thinking? Write it down!

Answer 23

hyy @K12Questions can you help me again please

Answer 24

It will take work. That's where you should start.

Answer 25

thanks I can see that but I need someone to walk me though it

Answer 26

You just had three walk-through examples. How may do you think it will take? Usually, it's just enough to get someone else to do your homework for you. Is that really how you wish to be perceived? Answering my questions and showing your work will be FAR MORE beneficial than any more walk-throughs.
