What is the value of the expression (–2)5? A. 32 B. 10 C. –10 D. –32 HELP ME
C
\(-2 \times -2 \times -2 \times -2 \times -2 =~?\) @keynote Don't give answers.
Is it (-2)5 or \((-2)^5\)?
Yes, remember not to give out answers. Try to guide the asker to the answer :D
@chosenmatt
32?
Oh yeah.. ^^^^^^^^^^^^^^^^^
No, first. Is it \((-2)^5\) or is it \(-2(5)\)?
(-2)5
Okay, are you sure the 5 isn't small and at the top?
If it isn't, then you just multiply: \(-2 \times 5\)
Ah, okay, (-2)5 is the same as -2 x 5 When multiplying a negative with a positive, the answer is always negative.
5 is at the top like 2 and an high 5 lol
Remember: \(Negative \times Positive = Negative\) \(Positive \times Negative = Negative\) \(Positive \times Positive = Positive\) \(Negative \times Negative = Negative\)
So -2 and 5 is the same size?? o_o
Right, so it's: \(-2 \times -2 \times -2 \times -2 \times -2\)
no 5 is on top of 2 lol
You mean -2, right?
Okay, if 5 is on the top of -2, like this: \((-2)^5\) Then you multiply -2 by itself, 5 times, giving you: \(-2 \times -2 \times -2 \times -2 \times -2\)
yeah lol \[-2 ^{5}\]
parentheses is around -2 tho
@sleepyjess
Yeah, just multiply: \(-2 \times -2 \times -2 \times -2 \times -2\)
s0 32?
No..check again.
-32?
Yep! \(-2 \times -2 \times -2 \times -2 \times -2\) \(4 \times -2 \times -2 \times -2\) \(-8 \times -2 \times -2\) \(16 \times -2\) \(-32~\Large\color{lime} \checkmark\)
