pleaswe help

jim_thompson5910 · Answer

how many copies of `-2` are being multiplied here?

j3nny0rtiz · Answer

5

quantummechanics · Answer

As @jim_thompson5910 has requested, the exponents tell you how many times you multiply the number by itself. 
For example: $$x^4 = (x)(x)(x)(x)$$

jim_thompson5910 · Answer

yes, 5

so `(-2) (-2) (-2) (-2) (-2)` is equivalent to `(-2)^5`

it's a shorthand way of writing out all that multiplication

jim_thompson5910 · Answer

it looks like they have a typo somewhere

j3nny0rtiz · Answer

the answers I have are diferent

quantummechanics · Answer

Maybe a (-2) was added by mistake in the question?

jim_thompson5910 · Answer

yeah which is why I'm thinking there's a typo

quantummechanics · Answer

Would you mind checking if it is (-2) (-2) (-2) (-2)  instead of (-2) (-2) (-2) (-2) (-2)

j3nny0rtiz · Answer

its 5 times

jim_thompson5910 · Answer

I think your teacher made a typo and there should be (-2)^5 in there somewhere. So you'll have to ask him/her about it

Thank you @jim_thompson5910
