i actually did try and do this problem, but i think im just.. really wrong.. so i need help. ... and this is my first time to do anything with the exponent 'law' so it would be nice if you could give me 'hints' or somthing to solve this sorta problem.
how would i simplify 12x^9 / 4x^4

12x^9 / 4x^4
So can you split it into two parts:
12/4 =3
x^9/x^4 is the same as saying x^9-4=x^5
-->Note: when you divide exponents with the same base, subtract the exponents like I did
So your answer is 3x^5

For the base numbers (12, 4) just simplify as usual which would give you a 3. For exponents in order to simplify them you have to subract the exponent in the Numerator from the exponent in the Denominator, this will give you x^5.
Your answer is the result of those two.... see below...
3x^5

how would i simplify 12x^9 / 4x^4
12 * ( x^9 ) / [ 4 * x^4 ]
= ( 12/4 ) * [ (x^9) / (x^4) ]
= 3 * x^(9 - 4)
= 3 x^5
The proof that (x^9) / (x^4) = x^(9-4) is
x^9 = x * x * x * x * x * x * x * x * x
x^4 = x * x * x * x
(x^9) / (x^4)
= ( x * x * x * x * x * x * x * x * x) / ( x * x * x * x)
Cancel the 4 x's from the numerator that match the 4 x's in the denominator.
The number of x's remaining is (9 - 4) = 5.

When dividing, you subtract exponents.
12x^9 / 4x^4 12/4 =3 x^9/x^4 = x^9-4 = x^5
So your answer is 3x^5. !

12x^9/4x^4 ...
divide 12/4 = 3
3x^9/x^4
x^9 = x^4*x^5 split it up ...here you're using the rule where
if you have like bases...you add the exponenets.
Now x^4/x^4 cancels out
=3x^5 your answer.

just divide 12 and 4 (you get 3) and for the exponents just subtract. (ur answere is 3x^5)

27m^6 whenever you're coping with something indoors a chain of parenthesis, what's outdoors the parenthesis impacts each ingredient indoors them. consequently: (3m^2)^3 (3)^3 + (m^2)^3 27+m^6 27m^6
