Question
Find the roots
v1=−90e25e,v2=90e25e
Alternative Form
v1≈−0.302676,v2≈0.302676
Evaluate
e5−1620v2
To find the roots of the expression,set the expression equal to 0
e5−1620v2=0
Move the constant to the right-hand side and change its sign
−1620v2=0−e5
Removing 0 doesn't change the value,so remove it from the expression
−1620v2=−e5
Change the signs on both sides of the equation
1620v2=e5
Divide both sides
16201620v2=1620e5
Divide the numbers
v2=1620e5
Take the root of both sides of the equation and remember to use both positive and negative roots
v=±1620e5
