Well done for trying. Can you show me your working, either in text, or using Draw, or by scanning/taking a photo and using Attach File?

sure

anonymous · Answer

Great

anonymous · Answer

(-3x^2)^3=-27x^6.
(9x^3)^-1=-9x^-3
then i multiplied the two and got 243x^3

anonymous · Answer

Ok, what should the answer be?

anonymous · Answer

243x^3

anonymous · Answer

oh nvm. what  SHOULD it be, lol.

anonymous · Answer

well im thinking i need to get a negative exponent. so that i'll have to put the x in the denominator of a fraction
