Question

SR18+ SR 4y^3-2SR y^3 -SR 48y^2
solve this radical!

Answer 1

Try once

Answer 2

question is
\[\sqrt{18} + \sqrt{4y^3} -2\sqrt{y^3}-\sqrt{48y^2}\]

Answer 3

ive been working them out, im checking my answer which i got. 2y^2+3y SR2y. is that right?

Answer 4

no it is not correct

Answer 5

because first term is \[\sqrt{18}= 3\sqrt{2}\]

Answer 6

\[\sqrt{18}+\sqrt{4y ^{3}}-2\sqrt{y ^{3}}-\sqrt{48y ^{2}}\] Do them one at a time, slowly and carefully.

Answer 7

sheg, has worked the first one, look at the next two, and figure out why you can just throw them away !

Answer 8

@riyamoon it is still not correct
If your helping me with my question its not letting me post. i got \[3\sqrt{2}+6\sqrt{3}\]

Answer 9

is that right?

Answer 10

no it is not correct

Answer 11

my computer is being gay...then idk what im doing wrong

Answer 12

The last term can be also expressed as\[\sqrt{16 * 3 y ^{2}}\] Does that help?

Answer 13

Note that two of those are perfect squares!

Answer 14

Now you can work it

Answer 15

@riyamoon are you trying to throwing the answer blindly without doing the calculations

Answer 16

@riyamoon, what is the square root of 16, what is the square root of \[y ^{2}????\]

Answer 17

riya u need to work hard

Answer 18

Looking at each term of the expressionL\[\sqrt{18}=\sqrt{9}\sqrt{2}=3\sqrt{2}\]
Looking at the next two,\[+\sqrt{4y ^{3}}-2\sqrt{y ^{3}}=+2\sqrt{y ^{3}}-2\sqrt{y ^{3}}=0\]
That leaves the last one for you, and you were shown how it can be broken down and solved.

Answer 19

\[\sqrt{18} +\sqrt{4y^3} - 2\sqrt{y^3} - \sqrt{48y^2}\]
\[=3\sqrt{2} +2y\sqrt{y} - 2y\sqrt{y} - 4y\sqrt{3}\]
\[=3\sqrt{2} - 4y\sqrt{3}\]
