Question

Help basic math

Answer 1

Ok. Um. Can you keep guiding me?

Answer 2

yeah no problem

Answer 3

Thank you.

Answer 4

Ok. I have the final answer. I was just wondering how to get there.

So we know 2.

Answer 5

what was your final answer ?

Answer 6

wait hold on I think I misread this lol

Answer 7

It is256/1

Answer 8

\[x = \frac{ 1 }{ y} = 2 \]

Answer 9

Well, I honestly don't know if the 1/y is supposed to be an exponent or not. It looks like it is almost treated as an exponent

Answer 10

wow i thought the 1/y was an exponent too

Answer 11

All I know is the and is 256 / 1

Answer 12

if it was an exponent y could equal .5 to be 2

Answer 13

okay yeah @AmTran_Bus I got it now. @sweetburger lol I looked at it and thought the same thing

Answer 14

\[x = \frac{ 1 }{ y } =2 \]

we know that x = 2

and that 1/y must also equal 2

\[\frac{ 1 }{ (y) } = \frac{ 1 }{ \frac{ 1 }{ 2 } } = 2 \]

Answer 15

Ok. I do understand that.

Answer 16

\[\frac{ x^{4} }{ y^{4}} = \frac{ (2)^{4} }{ (\frac{ 1 }{ 2 } )^{4}}\]

= \[\frac{ 16 }{ \frac{ 1 }{ 16 } } \]

Answer 17

Is that it? Wow. So easy. Thanks for helping me. That one was laid out poorly IMO

Answer 18

@AmTran_Bus take a look

Answer 19

now it is 16 * 16

Answer 20

\[\frac{ 16*16 }{ \frac{ 1 }{ \cancel\16 }*\cancel\16 } = \frac{ 16*16 }{ 1 } = 256 \]

Answer 21

Right. This is for the GRE. I'm good with how to actually do the math, it is the setting up that is killing me.
