kaheart [24]

Answer:

The solution of the equation is x=\frac{(ln4)-5}{2} ⇒ 3rd answer

Step-by-step explanation:

* Lets explain how to solve this problem

- The function f(x) = e^x is called the (natural) exponential function

- The natural logarithm (㏑), or logarithm to base e, is the inverse

 function to the natural exponential function

∵ e^{2x+5}=4 is an exponential function

∴ We can solve it by using the inverse of e (㏑)

- Remember:

# ln(e)=1

# ln(e^{m})=m(ln(e))=m

- Insert ln in both sides

∴ ln(e^{2x+5})=ln(4)

∵ ln(e^{2x+5})=(2x+5)ln(e)=2x+5

∴ 2x + 5 = ㏑(4)

- Subtract 5 from both sides

∴ 2x = ㏑(4) - 5

- Divide both sides by 2 to find x

∴ x=\frac{ln(4)-5}{2}

* The solution of the equation is x=\frac{(ln4)-5}{2}
