Question

Simplify the following expression.
square root of -121-24

Answer 1

\[\sqrt{-121-24}\]
\[\sqrt{-145}\]

\[\sqrt{-1}\sqrt{145}\]
\[i\sqrt{145}\]

Answer 2

can you figureo ut what youcan pull out of the square root now?

Answer 3

how do you get 145 it said that you times your radical at the end to get the final answer

Answer 4

the square root of -121 is 11 but i sqaure root of -24 is 4*6 can you help me please

Answer 5

so your question is

\[\sqrt{-121}-\sqrt{-24}\]

Answer 6

yea

Answer 7

i think i finally got it is the answer 2√6 -24

Answer 8

so sqrt(-121) =

Answer 9

and sqrt(-24) =

Answer 10

yes

Answer 11

and you have to simplify

Answer 12

sqrt(-121) = sqrt((- (11*11)) =

Answer 13

= 11 sqrt(-1) =

Answer 14

Answer 15

so can you continue it with sqrt(-24) ?

Answer 16

not is right

there is a minus too

Answer 17

what is not right

Answer 18

so there is

sqrt(-121) - sqrt(-24) =

yes ,this is the exercise and little up was evalueted sqrt24 = 2sqrt6

ok ?
