Question

how do you do -4 times (-4) with a neg one exponet ? (Zero and negative exponets) explain with answer please.

Answer 1

Do you mean this?\[-4*(-4)^{-1}\]

Answer 2

yes

Answer 3

Negative one exponent means this:\[a^{-1}=\frac{1}{a}\]

Answer 4

i just wrote what the paper said so how do you do it ?

Answer 5

would it be like 1 over 4 some

Answer 6

Use what I said before to change the one with the negative exponent.\[-4*\frac{1}{-4}\]

Answer 7

Now that the negative exponent is gone, do you know how to do the rest?

Answer 8

is it like 1 over 16 , sorry if I'm getting this sooo wrong.

Answer 9

No worries. -4 is the same as -4 divided by 1 so you get this.\[\frac{-4}{1}*\frac{1}{-4}\]Does it make sense now?

Answer 10

In case you didn't know, when you multiply fractions, you multiply the tops to get the new top and you multiply the bottoms to get the new bottom.

Answer 11

I still don't get it. ugh i'm so dumb lol this makes no sense .

Answer 12

Which step is the first one you don't get?
\[-4*(-4)^{-1}\]Step 1:\[-4*\frac{1}{-4}\]Step 2:\[\frac{-4}{1}*\frac{1}{-4}\]In case you were wondering, that isn't the final answer. I just don't want to move on until you understand.

Answer 13

howd you get the extra one and i kinda get it now what do you do after ?

Answer 14

Which extra one? The one under the -4? If you're talking about that one, then the reason is that -4 divided by 1 is the same as -4 so I can replace -4 with -4/1

Answer 15

Yeah oh okay i see

Answer 16

Now we have two fractions that we're multiplying. When you multiply the fractions, just multiply the tops to get the new top and multiply the bottoms to get the new bottom. Like this:\[\frac{1}{2}*\frac{4}{1}=\frac{4}{2}\]Which is 2 because 4 divided by 2 is 2. So do the same thing in your problem.

Answer 17

-4 over - 4 or no waht

Answer 18

yes

Answer 19

so would i haft to get rid of the negs if so how

Answer 20

-4 over -4 is correct.\[\frac{-4}{-4}\]So you got this. Fractions are just division. So what's -4 divided by -4?

Answer 21

1

Answer 22

And that's the answer.

Answer 23

1 is the answer o-o

Answer 24

Yeah, don't you hate it when math classes make you go through problems that confuse you and then just end up in something like 1? XD

Answer 25
