Question

Find the exact value of the radical expression in simplest form. c√c + √7x - 2c√c

Answer 1

we see there is a like term of csqrtc so we get -c(sqrtc) + sqrt7x

Answer 2

We always add like terms.

Answer 3

Same as in rational expressions with variables of different powers.

Answer 4

It gives me only 4 choices though... 11c, c√c, 11c√c, or 11√c.

Answer 5

I agree with Saif because I don't know what to do otherwise.

Answer 6

Is your question correct?

Answer 7

Yup, sure is. It's probably the school.

Answer 8

What about this one? Find the exact value of the radical expression in simplest form. √169 - √50 - √8

Answer 9

For this one,
we have to factor the terms out.

Answer 10

i mean factor the square roots .

Answer 11

Lol, dont sleep in class! ;D

Answer 12

I don't. I'm actually really dedicated. Algebra is just really hard for me.

Answer 16

I can't do any better than that guy^

Answer 17

guy? :P well, i appreciate it anyway.

Answer 18

The guy in the vid @fallingangel

Answer 19

√169 - √50 - √8 for this radical we know √169 = 13, √50 = √2*25 =√2*√25= 5*√2 and for √8 = √4*2 = √4*√2 = 2√2

so now let us plug this in so we got 13 -5√2 - 2√2 = 13 -7√2 :)
