Question

help me math expression :/

Answer 1

???where??????

Answer 2

Everywhere

Answer 3

64-11

Answer 4

wait what?

Answer 5

\[(8 +√11 )(8 –√11 ) \rightarrow 8*8-8\sqrt{11}+8\sqrt{11}-\sqrt{11}*\sqrt{11}\]

which simplified you get \[64-11\] \[-\sqrt{11}*\sqrt{11}=-11\] the square root cancels out

Answer 6

oh i get that

Answer 7

yup just remember the FOIL concept and you will be good

Answer 8

okay i will so the answer then would be 64 +/11

Answer 9

No it would be 64 - 11

Answer 10

or 53

Answer 11

oh I see it got thankyou for your help :)

Answer 12

good eye @Snipa420 i didnt see the 53 option the answer is 53

Answer 13

Go for it

Answer 14

nope the answer would be A

Answer 15

first thing you must look at is the square root. you can see that they aren't the same

when adding radicals together they must have the same radical.

Answer 16

we can see the 1st one is \[2\sqrt{6}\] and the 2nd one is \[3\sqrt{96}\]

you now have to find 2 multiples that would equal 96 so you can remain with a \[\sqrt{6}\]

Answer 17

\[3\sqrt{16*6}=3\sqrt{16}*\sqrt{6}\rightarrow 3*4\sqrt{6}\rightarrow 12\sqrt{6}\]

Answer 18

and all you have to do is add them together

You welcome anytime!!

Answer 19

now i can do the rest with no problem thanks again

Answer 20

yup
