  1. Part A:
    325+log(x)=4\frac{32}{5 + \log(x)} = 4

  2. Part B:
    logy(2x+12)=2\log_y (2x + 12) = 2

Let's proceed to solve these equations step by step.


Solution for Part A:

Given the equation: 325+log(x)=4\frac{32}{5 + \log(x)} = 4

  1. Step 1: Multiply both sides by 5+log(x)5 + \log(x) to eliminate the denominator: 32=4×(5+log(x))32 = 4 \times (5 + \log(x))

  2. Step 2: Simplify the right side: 32=20+4log(x)32 = 20 + 4 \log(x)

  3. Step 3: Subtract 20 from both sides: 12=4log(x)12 = 4 \log(x)

  4. Step 4: Divide both sides by 4: 3=log(x)3 = \log(x)

  5. Step 5: Exponentiate both sides to remove the logarithm: x=103x = 10^3 x=1000x = 1000

Thus, the solution for Part A is: x=1000x = 1000


Solution for Part B:

Given the equation: logy(2x+12)=2\log_y (2x + 12) = 2

  1. Step 1: Convert the logarithmic equation to its exponential form: 2x+12=y22x + 12 = y^2

  2. Step 2: Solve for xx: 2x=y2122x = y^2 - 12 x=y2122x = \frac{y^2 - 12}{2}

Thus, the solution for Part B is: x=y2122x = \frac{y^2 - 12}{2}
