How to get the answer

2*x^4*z^3

Step-by-step explanation:

To answer this kind of question, you first start rearranging the terms in the numerator and denominator, so you don't get confused.

3x^3 * 4x^3 * z^4 / 2x * x * 3z

Now you multiply like parts in the numerator and denominator to keep it simple.

(3x^3 * 4x^3) * z^4 / (2x * x) * 3z

3x^3 * 4x^3 = 12x^6

2x * x = 2x^2

12x^6 * z^4 / 2x^2 * 3z

Now divide like terms that are in the numerator and denominator so multiplying later will be easier.

12x^6 / 2x ^ 2 * z^4 / 3z

12x^6 / 2x^2 = 6x^4

z^4/3z = z^3 / 3

Now you multiply both terms,

6x^4 * z^3/3

2*x^4*z^3

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
