Question

Write each expression in the simplest form.
1. (-8y^9)^1/3
2. (x^1/3 / y^-2/3)^9

Answer 1

whoops forgot to put this into the algebra section, but I still need some guidance

Answer 2

\[\large\rm a^{x^{y}}=a^{xy} \]

Answer 3

Stil need help?

Answer 4

um yeah just a little

Answer 5

okay so what is 3√-8 ?

Answer 6

-2?

Answer 7

Perfect
so whats 3√y^9

Answer 8

i'm not sure because it's just a variable

Answer 9

would I have to do something with the exponent or?

Answer 10

Apply the formula I gave you

Answer 11

So does this mean that (-8y^9)^1/3 is technically already simplified?

Answer 12

No it isn't simplified
But you can break it like 3√-8 * 3√y^9

Answer 13

i multiply these two together correct?

Answer 14

yep

Answer 15

about -4 ?

Answer 16

no, first simplify the brackets then multiply
(3√-8 ) * (3√y^9)

Answer 17

oh okay, so it's -2 and 2.08
