Consider the equation 2*e^-6w=95 Solve the equation for w. Express the solution as a logarithm in base-e

pishuonlain [190]

Answer:

$log_e \Big (\dfrac{95}{2} \Big )= {-6w}$

Step-by-step explanation:

From the given information:

We need to find the value of w

$2*e^{-6w}= 95$

Divide both sutiet sl???ides. VVVVV

$e^{-6w}= \dfrac{95}{2}$

Taking the logarithim in base in e for both sides:

$log_e \Big (\dfrac{95}{2} \Big )= {-6w}$
