Question

help!

Answer 1

\[4\times \sqrt{3}\times \sqrt{3}\]

Answer 2

is it possible to simplify this?

Answer 3

yes

Answer 4

4 x 3 = 12
3^1/2 x 3^1/2 = 3

Answer 5

\[\sqrt{3} * \sqrt{3} = \sqrt{3^{2}}= ?\]

Answer 6

i don't get what you guys are telling me.

Answer 7

here. \[\sqrt{3}*\sqrt{3}=3^{1/2}*3^{1/2}\]

Answer 8

3.5 * 3.5?

Answer 9

and do you understand indices

Answer 10

no

Answer 11

never even heard of that

Answer 12

\[2^{3}*2^{2}=2^{3}+^{2}\]

Answer 13

oh yeah i know that.

Answer 14

exponent laws

Answer 15

meaning that when you have same base multiplying each other with different or same power you take one base and sum up the powers .

Answer 16

ah oh yeah, so 3^1?

Answer 17

yap. very correct

Answer 18

12 is the answer?

Answer 19

and we still have 4. so it will be 4*3 =12

Answer 20

yes.

Answer 21

but how did you know to put the 1/2 power for the sqrts of 3s?

Answer 22

because \[\sqrt{x}=x ^{1/2}\]

Answer 23

its a rule

Answer 24

oh i get it i think

Answer 25

because, x is, x * x

Answer 26

so also \[\sqrt[3]{8}=8^{1/3}\]

Answer 27

it's 2 of the same numbers to multiply each other.

Answer 28

o.O, how?

Answer 29

hmmmmm,... want to be busy now. you can fan and medal so that when am back we continue

Answer 30

ok thanks
