Question

Simplify. Write in radical form
(see comments for equation)

Answer 1

\[\left[\begin{matrix}x ^{3} & y ^{-2} \\ xy & \end{matrix}\right]^{-1/5}\]

Answer 2

what the hell is the fourth term :)

Answer 3

Whatoh wow that didn't come out right,
It's (x^y^-2/xy)^-1/5

Answer 4

What the hell did you type

Answer 5

x to the power of y to the power of negative two divided by xy whole thing to the power of one divided by five

Answer 6

yep...

Answer 7

and it's asking to simplify and write in radical form..

Answer 8

and you drawn a matrix? lol

Answer 9

hey, i'm new with the equations with open study the whole thing besides the -1/5 is in parenthesis

Answer 10

\[\Huge\left(x^{y^{\frac{-2}{xy}}}\right)^{\frac15}\]

Answer 11

Is this what you mean?

Answer 12

nope I'll try to draw it

Answer 13

oh that's why, you typed out x^ instead of x^3

Answer 14

yeah,

Answer 15

ok, simplify the things inside the parentheses first

Answer 16

lol

Answer 17

can't the exponents be added to get xy^1/xy ?

Answer 18

or (xy/xy)

Answer 19

no, because they have different bases

Answer 20

uh, okay?

Answer 21

\[\huge (\frac{ x^2 }{ y^3 })^{-1/5}\]
when multiplying exponents like this you do:
\[\huge (x^m)^n = x^{m*n}\]

Answer 22

@shamil98 is that it? it's only a 2pt question so I think that will do it for me honestly, it's the only one like that on it too so..

Answer 23

or can't we multiply both the exponents by -1/5 ??

Answer 24

no you simplify this:
\[\huge \frac{ x^{3*\frac{ -1 }{ 5 }} }{ y^{2*\frac{ -1 }{ 5 }} }\]

Answer 25

then using the rule:
\[\huge x^{-n} = \frac {1}{x^n}\]

Answer 26

i got x^-.6/y=-.4
what are those decimals as fractions? my calculator wont show them
-.6 and -.4

Answer 27

Keep it in fractions..

Answer 28

and there is no need for a calculator here.

Answer 29

i don't know how to do that, i'm terrible with fractions

Answer 30

What is \[\huge 3 * \frac{ -1 }{ 5 }\]

Answer 31

i can't do mental math at all. like literally it does not click in my brain at all.
do i multiply 3x-1 and 3x5
-3/15 ??

Answer 32

or -1/5 ?

Answer 33

-3/5

Answer 34

\[\huge 3 * \frac{ -1 }{ 5 } = \frac{ 3 }{ 1 } *\frac{ -1 }{ 5 } = \frac{ 3*(-1) }{ 1*5 }\]

Answer 35

i made a typo earlier it is:
\[\huge \frac{ x^{2 * (-1/5)} }{ y^{3*(-1/5)} }\]

Answer 36

multiply the numbers first.. what do you get?
