Question : 4

Total: 40

Simplify

3 q \times 12 p q

Solution:

Concept:

Multiply the numbers and add the exponents of like variables.

Explanation:

Write the expression with coefficients and variables grouped:

3 q \times 12 p q = (3 \times 12) \times p \times (q \times q)

q

means

q^1

, so multiplying

q^1 \times q^1

gives

q^{1+1} = q^2

Therefore,

3 q \times 12 p q = 36 p q^2

Answer:

36 p q^{2}
