Question
Simplify the expression
2f3−1
Evaluate
f3×2−1
Solution
2f3−1
Show Solution

Find the roots
f=234
Alternative Form
f≈0.793701
Evaluate
f3×2−1
To find the roots of the expression,set the expression equal to 0
f3×2−1=0
Use the commutative property to reorder the terms
2f3−1=0
Move the constant to the right-hand side and change its sign
2f3=0+1
Removing 0 doesn't change the value,so remove it from the expression
2f3=1
Divide both sides
22f3=21
Divide the numbers
f3=21
Take the 3-th root on both sides of the equation
3f3=321
Calculate
f=321
