{2^(3x-1)+10} ÷21 = 18 |
|
Answer» Answer: ☺☺☺ Step-by-step explanation: Multiply both SIDES of the equation by 21.
23x - 1 + 10 = 278
Subtract 10 on both sides of the equation.
23x - 1 = 268
LOG both sides of the equation and BRING all exponents as the coefficient of logs.
(3x - 1)Log(2) = Log(268)
3x - 1 = Log(268) / Log(2)
3x = [Log(268) / Log(2)] + 1
x = (1/3) * [(Log(268) / Log(2)) + 1] |
