Question

Can somebody help me with this? (radicals)

Answer 1

I think i do.. (sorry for the long wait to reply, the school computer keeps crashing and shutting off)

Answer 2

\(\bf \large{ \textit{keep in mind that}\qquad
\sqrt[n]{a^nbc^n}\implies ac\sqrt[n]{b}\\ \quad \\
\textit{also that }\qquad a^n\cdot a^m\implies a^{n+m}}\)

Answer 3

Okay thank you

Answer 4

does that clarify any or all misunderstandings or do i need to explain it still?

Answer 5

I still need help, i barely understand..

Answer 6

ok the first step is completely correct

pointing to the 2nd line jdoe wrote, its just a property of exponents

Answer 7

the second step kind of skips a step

\[\sqrt[6]{x^6 x^7}= \sqrt[6]{x^6} \sqrt[6]{x^7}\]

Answer 8

its just breaking up the radical

Answer 9

and so \[\sqrt[6]{x^6}= x\]

just like
\[\sqrt[2]{x^2}=x\]

Answer 10

any questions at this point?

Answer 11

Umm.. is that a 0 for a radical you just wrote or is it a 6?

Answer 12

its a 6

zero wouldnt make much sense

Answer 13

Okay good point.. i have no questions.. i guess i'm slowly getting it, radicals are just very confusing for me..

Answer 14

if it helps, you can convert radicals into exponents

Answer 15

\[\large{\sqrt[n] {x} = x ^ \frac{1}{n}}\]

Answer 16

if thats too confusing, then jsut ignore it

Answer 17

Ohh that makes sense actually

Answer 18

Yeah, but the question i posted is still confusing.. I think i'm going to use google to help me because then i can read it at my own pase to figure out how to actually solve radicals

Answer 19

what part is confusing?

Answer 20

Basically all of it.. I mean i understand a little but the whole thing basically doesn't make sense to me, The program i'm using to do this work doesn't very well teach us how to do radicals
