Q. 350.2w=720 3 \cdot 5^{0.2 w}=720 \newlineWhat is the solution of the equation?\newlineRound your answer, if necessary, to the nearest thousandth.\newlinew w \approx \newline \square
  1. Isolate variable term: First, let's isolate the term with the variable ww by dividing both sides of the equation by 33.5(0.2w)=72035^{(0.2w)} = \frac{720}{3}5(0.2w)=2405^{(0.2w)} = 240
  2. Get rid of exponent: Now, we need to get rid of the exponent. We can do this by taking the logarithm of both sides. Let's use the natural logarithm (ln) for this.\newlineln(50.2w)=ln(240)\ln(5^{0.2w}) = \ln(240)
  3. Take natural logarithm: Using the property of logarithms that allows us to move the exponent to the front, we get:\newline0.2wln(5)=ln(240)0.2w \cdot \ln(5) = \ln(240)
  4. Divide by ln(5)\ln(5): Now, we'll divide both sides by ln(5)\ln(5) to solve for ww.\newlinew=ln(240)0.2×ln(5)w = \frac{\ln(240)}{0.2 \times \ln(5)}
  5. Calculate final value: Let's do the calculation.\newlinewln(240)0.2×ln(5)w \approx \frac{\ln(240)}{0.2 \times \ln(5)}\newlinew22.180709777918250.2×1.6094379124341003w \approx \frac{22.18070977791825}{0.2 \times 1.6094379124341003}\newlinew22.180709777918250.32188758248682006w \approx \frac{22.18070977791825}{0.32188758248682006}\newlinew68.906w \approx 68.906
