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
  1. Isolate exponential term: First, we need to isolate the exponential term on one side of the equation.\newline3×50.2w=7203 \times 5^{0.2 w} = 720\newlineDivide both sides by 33 to isolate the exponential term.\newline50.2w=72035^{0.2 w} = \frac{720}{3}\newline50.2w=2405^{0.2 w} = 240
  2. Apply logarithm: Now, apply the logarithm to both sides of the equation to solve for the exponent.\newlinelog(50.2w)=log(240)\log(5^{0.2 w}) = \log(240)\newlineUse the power property of logarithms to bring down the exponent.\newline0.2wlog(5)=log(240)0.2 w \cdot \log(5) = \log(240)
  3. Isolate ww: Isolate ww by dividing both sides of the equation by (0.2×log(5))(0.2 \times \log(5)).
    w=log(240)(0.2×log(5))w = \frac{\log(240)}{(0.2 \times \log(5))}
    Calculate the value of ww using a calculator.
    wlog(240)(0.2×log(5))w \approx \frac{\log(240)}{(0.2 \times \log(5))}
    w2.3802112417(0.2×0.6989700043)w \approx \frac{2.3802112417}{(0.2 \times 0.6989700043)}
    w2.38021124170.13979400086w \approx \frac{2.3802112417}{0.13979400086}
