Answer» Correct Answer - Option 3 : -2/3 Formula used: am × an = am + n (a × b)m = am × bm Calculation: By using formula ⇒ (2 × 3)2 × 33x = (33)3x + 2 × 22 ⇒ 22 × 32 × 33x = 39x + 6 × 22 ⇒ 33x + 2 = 39x + 6 Now, ccompairing power ⇒ 3x + 2 = 9x + 6 ⇒ 6x = -4 ⇒ x = -4/6 ⇒ x = -2/3 ∴ The required value of 'x' is -2/3. |
