What is the true solution to 2 In eln 5x – 2 In 15?
babunello [35]

Answer:

x = 49.84

Step-by-step explanation:

We are given an equation of unknown x and we have to solve the equation for x.

2\ln(e\ln5x)-2\ln15 =0

⇒ ln(e\ln5x) = \ln15

⇒ \ln e + \ln \ln 5x = \ln 15 {Since we know that  ln AB =ln A + ln B}

⇒ \ln \ln 5x = \ln 15 -\ln e

⇒ \ln \ln 5x=\ln \frac{15}{e} {Since we know that ln A/B = ln A - ln B}

⇒ \ln 5x = \frac{15}{e}

⇒ 5x = e^{\frac{15}{e} }

⇒ x = \frac{1}{5} e^{\frac{15}{e} }{Converting logarithm to exponent form}

⇒ x = 49.84 (Approximate) (Answer)

Answer:

  $12,720

Step-by-step explanation:

The amount is given by the formula ...

  A = P(1 +rt)

where P is the principal, invested at rate r for t years.

  A = $12,000(1 +0.06·1) = $12,720

The total amount after 1 year is $12,720.
