If 4 x + 3 = 112 + 8 × 4 x ; find (18x) 3x .

Given, ⇒ 4 x + 3 = 112 + 8 × 4 x ⇒ 4 x .4 3 = 8(14 + 4 x ) ⇒ 64.4 x = 8(14 + 4 x ) ⇒ = 14 + 4 x ⇒ 8.4 x = 14 + 4 x ⇒ 8.4 x - 4 x = 14 ⇒ 4 x (8 - 1) = 14 ⇒ 7.4 x = 14 ⇒ 4 x = ⇒ (2 2 ) x = 2 ⇒ 2 2x = 2 1 ⇒ 2x = 1 ⇒ x = . Substituting value of x in (18x) 3x , we get : Hence, (18x) 3x = 27.
