samantharandix 2 years ago 1.Write and exponent . (-4)(-4) is it -4^2 i am so bad at this and i cannot wrap my head around it , can someone show me how to do it

1. zerosniper123

-4^2 just means (-4)(-4). If you had a problem that asked to write (-5)(-5)(-5)(-5) as a exponent, then your answer would be -5^how many (-5) there are...So its -5^4. Hope this helps :)

Are you sure , its telling me to show my work ,

3. zepdrix

$\large -4^2 \ne (-4)^2$Careful! Make sure to include the brackets! :)

4. samantharandix

so the answer is (-4)2 :S?

5. zepdrix

Mmmmm yah that's probably what you're suppose to do :) The wording on your question is kinda confusing lol. "Write and exponential" :o

6. zepdrix

and exponent* blah...

7. samantharandix

this is my question 1.write an exponent.show your work ,(-4)(-4)

8. samantharandix

write using a exponent** sorry

9. zepdrix

$\large x \cdot x = x^2$$\large 3 \cdot 3 =3^2$ Applying this gives us, $\large (-4)\cdot(-4)=(-4)^2$ So yah I guess that's what you were looking for :) To simply introduce an exponent so it looks simpler.

thank you!

Yes (-4)(-4)=(-4)^2=16(positive) -(4)(4) =-4^2 =-16(negative)
