You can put this solution on YOUR website! I'm not good at algebra and really don't understand the concept of polynomials. The problem that I am stuck on is
45a^4b^3
________
15a^b^2 =
:
Are you sure this right: 45 * a^4* b^3 make sense but
15 * a^ b^2, is ambiguous, is b an exponent of 'a' or what?
:
If it were like this (you meant b^2):
:
45*a^4*b^3
-----------
15*a^2*b^2 =
:
You can divide like terms and remember when you divide, you subtract the exponents in the denominator from the exponents in the numberator
:
Take each term individually
Of course you know 45/15 = 3, then
:
3 * a^(4-2) * b^(3-2) = 3*a^2*b
:
Even if this is not the exact problem you have, it should illustrate the rules of dividing when you have exponents.
