Question

Express the radical in simplest form: /121a^3b^2

the "/" = sqrt i dunno how to type it :/

Answer 1

help please :(

Answer 2

\[\sqrt{121a^{3}b^{2}}\]
right?

Answer 3

yes:)

Answer 4

ok use this important property
\[\sqrt{x^{2}} = x\]
so try to split everything into groups of 2
also 121 = 11^2 --> 11*11 = 121
\[\rightarrow \sqrt{11^{2}a^{2}ab^{2}}\]
i turned a^3 into a^2*a
now everything that is squared can be taken out of radical
\[\rightarrow 11ab \sqrt{a}\]

Answer 5

Would it be

11ab/a

Answer 6

nope just as i wrote it
\[11ab \sqrt{a}\]

Answer 7

lol i dunno how to do the sqrt symbol :P

But is that the right answer?

Answer 8

yes it is

haha go to equation button and type sqrt{ x }

Answer 9

thank you! :)
