Answer:
Step-by-step explanation:
*Move terms to the left and set equal to zero:
4㏒(√x) - ㏒(3x) - ㏒(x²) = 0
*simplify each term:
㏒(x²) - ㏒(3x) - ㏒(x²)
㏒(x²÷x²) -㏒(3x)
㏒(x²÷x² / 3x)
*cancel common factor x²:
㏒()
*rewrite to solve for x :
10⁰ =
1 =
1 · x = · x
1x =
*that would be our answer, however, the convention is to exclude the "1" in front of variables so we are left with:
x =
