Answer: 1,000,000,000,000,000,000,000,
Step-by-step explanation:

First, solve the parentheses:

Next, the exponential terms

Solve the multiplication:

Add and subtract:
15/x=75/100
15/x=3/4
times 4x both sides
4*15=3x
60=3x
divide both sides by 3
20=x
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 = 
Answer:
10-x ft long
Step-by-step explanation:
If it starts out 10ft long, and xft is taken away, then the remaining board would be 10-x ft long.
In terms of x, I believe it would just be 10-x ft long
