Question

If a = 2, b = 3, then the value of 2a²b³.​

Answer 1

• The value of 2a²b³ = 216.

⠀⠀⠀⠀

Given :

• Value of a = 2.
• Value of b = 3.

⠀

To Find :

• Value of 2a²b³.

⠀

Solution :

Given,

$\mapsto$ 2a²b³ ––––(1)

We have,

• a = 2.
• b = 3.

Now, substitute both the given values in equation (1),

So,

$\mapsto 2 {(2)}^{2} {(3)}^{3}$

We know that,

• 2² = 2 × 2.
• 3³ = 3 × 3 × 3.

$\mapsto 2(2 \times 2)(3 \times3 \times 3)$

$\mapsto 2(4)(27)$

$\mapsto 2 \times 4 \times 27$

Now, multiply small numbers (2 and 4).

We obtain,

$\mapsto 8 \times 27$

$\mapsto 216$

Hence,

The value of 2a²b³ is 216.
