Question

-4(-4) using exponents

Answer 1

x times x is \[x ^{2}\]
so put (-4) in for x

Answer 2

I don't know if I agree with that @TAKEBACKMATH

Answer 3

-4`2 is different from (-4)`2

Answer 4

\(-4 \times -4 = (-4)^2\)

Answer 5

are you supposed to write\[-2^{2}(-2^{2})\]or just write the answer as an exponent

Answer 6

@ChmE I think (-4)`2 is the answer

Answer 7

I agree with the answer. When i read the posted problem I understand as solve using exponents to get an answer. So we first have to rewrite it as I did to get your answer. But the negative signs will cancel.

Answer 8

yes then will in the answer

Answer 9

but teh question is to rewrite it as exponent and I believe its is trying to see if you know the difference between -4`2 and (-4)`2

Answer 10

Idk how you guys are evening considering leaving a negative sign in the answer. - times - is postive. even if its going to be squared

Answer 11

@ChmE the a question is "Rewrite it with exponents" so with that you leave the negatives in and of course when its calculated the negatives will go

Answer 12

ok so you are saying it is \[-2^{2}\times -(2^{2})\]

Answer 13

Yeah, but it says to express -4 times -4 as an exponent. Even though it would have to be +16, you have to consider that 16 can be reached by either \[4^{2}\] or \[-4^{2}\]

Answer 14

no its (-4)`2

Answer 15

I say the answer is \[2^{4}\]

Answer 16

@melbel yes you are right, but it just says express -4(-4) as a exponent, you guys are over thinking this

Answer 17

So if you're just looking at 16, you would have to consider both the pos and neg. Since the question specifically asks for the negative case, it would rule out the positive case. So it would have to be. \[-4^{2}\]

Answer 18

I know it is the same thing but that is using exponents the entire time

Answer 19

@ChmE you'd be wrong

Answer 20

exponent rules work with the same base

Answer 21

unless you're the teacher then we wont know unle x487 reposts the correct answer

Answer 22

which is what I did in a different way. You did 4^1 I chose 2^2

Answer 23

@melbel that's a different question to which you answer would be right

Answer 24

was just double checking my answer but how are you guys writing it a

Answer 25

Basically it's asking what is x time x expressed in exponents:
it's \[x^{2}\]
Plug in -4 for x.
\[-4^{2}\]

Answer 26

@melbel no (-4)`2

Answer 27

-4`2 means = the opposite of 4 squared
(-4)`2 means = negative 4 squared

Answer 28

Yeah, for some reason, this thing doesn't have negative notation like my calc does, just minus. So yeah, with that in mind \[(-4)^{2}\]
