Answer

y=6⋅2xy = 6 \cdot 2^x

Step-by-step solution

4 steps
  1. Apply the power rule of logarithms, clog⁡bM=log⁡b(Mc)c \log_b M = \log_b (M^c), to the term xlog⁡32x \log_3 2.

    xlog⁡32=log⁡3(2x)x \log_3 2 = \log_3 (2^x)
  2. Substitute this back into the original equation.

    log⁡3y=log⁡3(2x)+log⁡36\log_3 y = \log_3 (2^x) + \log_3 6
  3. Apply the product rule of logarithms, log⁡bM+log⁡bN=log⁡b(MN)\log_b M + \log_b N = \log_b (MN), to the right side of the equation.

    log⁡3y=log⁡3(2x×6)\log_3 y = \log_3 (2^x \times 6) log⁡3y=log⁡3(6⋅2x)\log_3 y = \log_3 (6 \cdot 2^x)
  4. Since the logarithms on both sides have the same base, we can equate their arguments.

    y=6⋅2xy = 6 \cdot 2^x
