Question

The coefficient of the product of (-5xy2) and (-4x2y) is
. The exponent of x in the product is
, and the exponent of y is
.

Answer 1

The product is: 20 x³ y³.
The coefficient of the product is 20.
The exponent of x in the product is : 3
The exponent of y in the product is : 3.

Answer 2

Answer:

The coefficient of product=20

The exponent of x=3

The exponent of y=3

Step-by-step explanation:

$\text{Given the two terms }(-5xy^2)\text{ and }(-4x^2y)$

we have to find the coefficient of product of above two terms and also the exponent of x and y in the product.

First we have to find the product of given terms

The product is

$(-5xy^2)\times (-4x^2y)$

Combining like terms

$(-5)(-4)\times (x\times x^2)\times (y^2\times y)$

$As, x^a\times x^b=x^{a+b}$

$20\times x^{1+2}\times y^{2+1}$

$20x^3y^3$

which is the required product.

The coefficient of product=20

The exponent of x=3

The exponent of y=3
