Question

Use a calculator to find an approximate solution to the equation. Round any intermediate work and steps to three decimal places. Show all of your steps in solving the equation for full credit. 2ln (x + 2.8) = 3.2

Answer 1

Answer:

x ≈ 2.15303

Step-by-step explanation:

Solve using algebra. The only concept you need to know is that e^ln() cancels each other out.

So I took the exponential of both side to try and cancel out the natural log.

Answer 2

The answer of an equation is 2.15303.

Given that,

• The equation is 2ln (x + 2.8) = 3.2.
• We need to solve the above equation.

Based on the above information, the calculation is as follows:

2ln (x + 2.8) = 3.2

$ln (x + 2.8) = 3.2 \div 2\\\\(x + 2.8) = e^{3.2\div 2}\\\\x = e^{3.2 \div 2} - 2.8$

= 2.15303.

Therefore we can conclude that the answer of an equation is 2.15303.
