D.
none of these

Answer 1

Please show your exponents using the ^ operator: It will make these problems much clearer. Also, I would have put this in 'Mathematics' rather than Chemistry.

First equation:
(6s^5)(2s^2)

Group your integer coefficients:
6*2 = 12

Group your s terms:
s^5 * s^2 = s^7 (multiplying like bases, just add the exponents)

So you have 12s^7 for the first part.

Second equation:
(3s^4)(4s^3)

Multiply integers:
3 * 4 = 12

Multiply s terms (add exponents):
s^4 * s^3 = s^7

This is also 12s^7.

Subtracting:
12s^7 - 12s^7 = 0

D) None of the above

Answer 2

Sloppy questioning. I can not understand anything.
