PLEASE HELP This is solving Exponential and Logarithmic Equations I got the other ones, but I don’t even know what this says to

QveST [7]

Answer:

Step-by-step explanation:

We have

$e^\frac{x}{2}^l^n^3 = 5\\$

$ln(e^\frac{x}{2}^l^n^3) = ln(5)\\\frac{x}{2}ln(3) = ln(5)\\\frac{x}{2} = \frac{ln(5)}{ln(3)} \\x = \frac{2ln(5)}{ln(3)}$

$x = 2.929947041$

to the third decimal is 2.930 (i might be wrong on the rounding part)
