Question
Find the roots
v1=−120e26e,v2=120e26e
Alternative Form
v1≈−0.248674,v2≈0.248674
Evaluate
e5−2400v2
To find the roots of the expression,set the expression equal to 0
e5−2400v2=0
Move the constant to the right-hand side and change its sign
−2400v2=0−e5
Removing 0 doesn't change the value,so remove it from the expression
−2400v2=−e5
Change the signs on both sides of the equation
2400v2=e5
Divide both sides
24002400v2=2400e5
Divide the numbers
v2=2400e5
Take the root of both sides of the equation and remember to use both positive and negative roots
v=±2400e5
