Question

For what value of x does 3^4x – 27x-3?

Answer 1

x = 1/18

Explanation:

Solve for x:

54 x - 3 = 0

Add 3 to both sides:

54 x + (3 - 3) = 3

3 - 3 = 0:

54 x = 3

Divide both sides of 54 x = 3 by 54:

(54 x)/54 = 3/54

54/54 = 1:

x = 3/54

The gcd of 3 and 54 is 3, so 3/54 = (3×1)/(3×18) = 3/3×1/18 = 1/18:

Answer: x = 1/18
