Negative exponents mean that you have to move the value to the numerator. Move the 2 and the x^-3 up, and you get 2x^3/y^5
^ means the next number is an exponent, btw. So 2x^3 is Two x cubed
and y^5 is y to the power of 5
sooo.....i dont get it. lol help walk me thorugh it
Okay, so the original equation is 1/2^-2 x^-3 y^5
The numbers that have negative exponents are 2 and x
If there's a negative exponent in the denominator, you want to move it to the numerator, and change the exponent to positive
So, if you move the 2^-2 to the top, you multiply it by the numerator, which is 1. You're left with 2. Pretty simple, 2 times 1
Right now, the equation is 2/x^-3 y^5
but thats not one of the answers
Now, you want to move the x^-3 up to the numerator. You do the same thing. Multiply the numerator by x^3, and you get 2x^3 / y^5 The y^5 stays on the bottom. That's fine.
the choices are: 16, -4, -1/32, or -16
Um, none of those would work. You can't solve it with no equal sign. Was that the whole equation?
thoes are the choices for the answer to the problem
We don't have any information on what to plug in for x or y, so it can't be solved. Are you 100% sure that's all the information you've been given, that picture and the answer choices?
oh! i forgot x=2 and y=4
sorry i thought it was on the picture
ok! I can help with that more now.
ok lol sorry
Hey girl come help me
So, let's plug them in. It's 2(2)^3 over (4)^5. The exponent for x is ONLY for x. Don't multiply x by two and then do the exponent, that's wrong. So, 2^3 is 8, times 2 is 16. 4^5 is 1024 (yes, big number, don't freak out.) You're left with 16/1024, or 1/64.
but thats not one of the choices. you mean 1/32?
i need help
i mean -1/32? @whovianchick
like i said the choices are the choices are: 16, -4, -1/32, or -16 @whovianchick
Wait no that's wrong, I did something wrong. When you plug it in, you get -1/32
I think that's it. Sorry! That would've been helpful to have the values at first
ok thank you for your help. @whovianchick
what do you want @number1gamer18
I NEED HELP
what comes after
I can't find a question in the feed
I'm not freaking stupid. Leave me alone
no but i do need help
