2a × 3a
= 2 × a × 3 × a
= 2 × 3 × a × a
= (2 × 3) × (a × a)
= 6 × a²
= 6a²
= 2 × a × 3 × a
= 2 × 3 × a × a
= (2 × 3) × (a × a)
= 6 × a²
= 6a²

2a x 3a = 6a^2
You can see it in two steps:
2 x 3 = 6
a x a = a^2
So you join these two products to get 6a^2

6a^2.

2 x 3 x a x a = 6 a²

2a * 3a =
2 * 3 * a^(1 + 1) =
6a^2
2 * 3 * a^(1 + 1) =
6a^2

(2a)*(3a) = (2)(3)(a)(a) = 6 a^2

2 a × 3 a
= 6 a^2
= 6 a^2

Multiplication is associative and commutative. Therefore:
2a × 3a
= (2 × a) × (3 × a)
= 2 × (a × 3) × a
= 2 × (3 × a) × a
= (2 × 3) × (a × a)
= 6 × a²
= 6a²

View it as
2a x 3a
= 2 x a x 3 x a
= 2 x 3 x a x a
= 6 x a x a
= 6 x a^2
= 6a^2
2a x 3a
= 2 x a x 3 x a
= 2 x 3 x a x a
= 6 x a x a
= 6 x a^2
= 6a^2

2a x 3a = 6a
