[(7x^3)(-x^7)]/14x^4
= (-7x^10)/14x^4
= -x^6/2

The carat symbol (^) is used for power symbols,
Lets rewrite your equation:
(7*x^3*(-x)^7) / (14*x^4)
7/14=1/2
(-x)^7 can be rewritten as ((-1)^7)*(x^7)
(-1)^7=-1
So your final coefficient is -(1/2)
Now add the powers of x in the numerator and subtract the powers of x in the denominator 3+7-4=6
The final simplification is -(1/2)*x^6.

(7x^3) * (x^7) / (14x^14) = ?
Add the exponents when multiplying them, subtract them when dividing, then multiply by the factors.
x^3 * x^7 = x^10
x^10 / x^14 = x^(-4) or 1/(x^4)
7/14 = 1/2
So the answer is 1 / (2x^4)

(7x^3)(x^7)/14x^4 =
The superscripted "powers" are added when you multiply SO...
7x^10/14x^4 =
The powers are subtracted when you divide so
7x^6/14 REDUCE TO
1x^6/2 or x^6/14

well after multiplication the top part comes out to be7x^21
and the bottom bart is 14x^4
Which after deviding by 7 = x^21 divided by 14x^4
Which can further be reduced to X^7 divided by 2x
For the power sign I used (shift 6)
Hope this helps.

the equation will be 7x^3 (-x^7) / 14x^4
first, simplify the numerical and literal coefficient of the numerator and denominator -x^7/2x
then simplify the variable x
that would be -x^6/2
and that is the answer for your equation
