Question

I really need help with this question

Answer 1

I need to simplify this expression rewrite it in radical form

Answer 2

anyone please

Answer 3

you should do that with the following properties:
\[\sqrt[n]{a}=a^{\frac{ 1 }{ n }}\]
\[a ^{n}.b ^{m}= a ^{n+m}\]

Answer 4

using those you can rewrite the expression as you want

Answer 5

and a,b,m,n are all real numbers

Answer 6

alright so would I get 1/2c[^{3/5}\] x -18/4d[^{1/6}\]

Answer 7

mm.. i would appreciate you to write your result with maths symbols because i didint understand what to got to.

Answer 8

1/2c^3/5 x -18/4 D ^1/6

Answer 9

where the x comes from?

Answer 10

multiplication symbol I will use a different one next time

Answer 11

what happened with the c factor?

Answer 12

try first to multiply all the fraction, so you will have them in only one fraction

Answer 13

and you wont have to care about them anymore

Answer 14

Example:
\[\frac{ 1 }{3 }a ^{-5}.\frac{ 1 }{ 3 }b ^{\frac{ 4 }{ 3 }}.\frac{ 1 }{ 2 }\sqrt[3]{b}=\frac{ 1 }{ 18 }(a ^{-5}.b ^{\frac{ 4 }{ 3 }}.\sqrt[3]{b})\]

Answer 15

and then you use the properties i gave you @sethgprescott :
\[\frac{ 1 }{ 18 }.(a ^{-5}.b ^{\frac{ 4 }{ 3 }}.b^ \frac{ 1 }{ 3 })=\frac{ 1 }{ 18 }(a^{-5}.b^{\frac{ 4 }{ 3 }+\frac{ 1 }{ 3 }})\]
