Find the value of x if 3 x 2 = 3 4 .

Given that, 3 x 2 = 3 4 Multiplying with 4 on both sides. ⇒ 3 x 2 × 4 = 3 4 × 4 ⇒ 3 x × 2 = 3 ⇒ 6 x = 3 Dividing with 3 on both sides. ⇒ 6 x 3 = 3 3 ⇒ 2 x = 1 Dividing with 2 on both sides ⇒ 2 x 2 = 1 2 ∴ x = 1 2

Find the value of l , if 2 l 3 - 5 = 4 .

Given that, 2 l 3 - 5 = 4 Adding 5 on both sides. ⇒ 2 I 3 - 5 + 5 = 4 + 5 ⇒ 2 l 3 = 4 + 5 ⇒ 2 3 × l = 9 Multiplying with 3 2 on both sides. ⇒ 2 3 × l × 3 2 = 9 × 3 2 ⇒ l = 27 2 ∴ l = 27 2
