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)

Help? Multi-Step Equations - Fractions. Solve the Equation.<br>PLEASE DO IT STEP BY STEP (visual)
GREYUIT [131]
R - 10/3 + 1/2 = -11/6...if u multiply everything by the common denominator 6, it will get rid of the fractions.

(6)r - 6(10/3) + 6(1/2) = 6(-11/6)
6r - 60/3 + 6/2 = - 66/6...simplify
6r - 20 + 3 = - 11
6r - 17 = -11
6r = -11 + 17
6r = 6
r = 6/6
r = 1 <===
