(2) 7b - 4b = .....
(3) 3p × p2 = .....
(4) 5m² × 3m² = .....
(5) (2x + 5y) × 3/x = .....
(6) (3x² + 4y) × (2x + 3y) = .....

Answer 1

(1) 5a^2
(2) 3b^2
(3) 3p^2
(4) 15m^2

Answer 2

Answer:

We need to find the solution of the given question:

1). 2a + 3a = 5a

2) 7b - 4b = 3b

3) 3p × 2p = 6$p^2$

4)$5m^2 \times 3m^2 = 15 m^{(2 + 2)} = 15m^4$

$5) (2x + 5y) \times \dfrac 3x = \dfrac{(2x \times 3 + 5y \times 3)}{x} = \dfrac{6x+ 15y}{x}$

$6) (3x^2 + 4y) \times (2x +3y) = 3x^2 \times 2x + 4y \times2x + 3x^2 \times 3y + 4y \times 3y \\= 6x^3 + 8xy + 9x^2y + 12y^2$
