1010n4−1
Show Solution

Find the roots
n1=−1010410103,n2=1010410103
Alternative Form
n1≈−0.177386,n2≈0.177386
Evaluate
n4×1010−1
To find the roots of the expression,set the expression equal to 0
n4×1010−1=0
Use the commutative property to reorder the terms
1010n4−1=0
Move the constant to the right-hand side and change its sign
1010n4=0+1
Removing 0 doesn't change the value,so remove it from the expression
1010n4=1
Divide both sides
10101010n4=10101
Divide the numbers
n4=10101
Take the root of both sides of the equation and remember to use both positive and negative roots
