Question

2(3^x - 3^x-1) = 324

Answer 1

Answer:

The value of x will be 5

Step-by-step explanation:

Given,

2( 3ˣ - 3ˣ⁻¹) = 324

=> ( 3ˣ - 3ˣ⁻¹) = 162

=> ( 3ˣ - 3ˣ/3) = 162

=> 3*3ˣ - 3ˣ = 162 x 3 = 486

=> 2*3ˣ = 486

=> 3ˣ = 486/2 = 243

=> 3ˣ = 3⁵

=> x = 5

Hence the value of x will be 5

Check

2(3⁵ - 3⁵⁻¹)

= 2(243 - 81)

= 2(162)

= 324
