Find the numerical coefficient of each of the terms: x³y²z, xy²z³, -3xy²z³, 5x³y²z, -7x²y²z²

Solution:

Given, the terms are x³y²z, xy²z³, -3xy²z³, 5x³y²z, -7x²y²z²

We have to find the numerical coefficient of each of the terms.

Numerical coefficient represents a numerical factor in a term.

Numerical coefficient of x³y²z = 1

Numerical coefficient of xy²z³ = 1

Numerical coefficient of -3xy²z³ = -3 × xy²z³

= -3

Numerical coefficient of 5x³y²z = 5 × x³y²z

= 5

Numerical coefficient of -7x²y²z² = -7 × x²y²z²

= -7

Therefore, the numerical coeffiecients are 1, 1, -3, 5 and -7.
