Question

LU UN
4. Find the product of
(i) 3x²y and - 4xy?​

Answer 1

Answer:

3x²y × ( - 4xy)

= - 12x³y²

Step-by-step explanation:

3x²y × (- 4xy)

Step 1

Multiply the constants

(3 and -4 in this case)

which gives, 3 × (-4) = -12

Step 2

Multiply the variables

(x²y and xy in this case)

which gives, x²y × xy = x³y²

since, x² × x = x³ and y × y = y²

Putting it together,

the ans is -12x³y²
