Question 360538: 8x exp. -4 times 2x exp. -3 times x exp. 7 = 16 ?
8 times 2 = 16
-4 + -3 = -7 exponent
so 16x exp. -7
then 16x exp. -7 times x exp. 7 = 16x exp. 0. (cause -7 +7=0)
so 16x exp. 0 = 16 (cause x to the 0 = 1)
Is that right?

Question 360544: If the answer is 1y exp. 4 over 3x exp. 10 would you just not write the 1 so you would only put y exp. 4 over 3x exp. 10?
The problem is:
6x exp -6, y exp 5 over 18x exp. 4, y exp. 1.
so that's 6x exp. -10, y exp. 4 over 18
so that's 6y exp 4 over 18x exp. 10
which is 1y exp 4 over 3x exp. 10
question is do you write the 1 next to the y or is it just y exp. 4 over 3x exp. 10?

Question 360535: WHAT IS THE ANSWER TO:
3x to the neg.9 exponent times 5x to the 5th exponent over 18x to the neg 4 exponent.
Tried to type it but couldn't get negative sign to work.
my answer is to add the two exponents -9 from 3x and 5 from 5x variable and got -4 exponent. Then multiplied 3 times 5 so = 15x to the -4 as numerator and 18x to the -4 for denominator. = 15x to the 0 as numerator over 18 for denominator. Now I don't know what to do with the 15x to the 0. I know x to the 0=1 so is 15x to the 0=15? Making my final answer 15/18=5/6 ?
