6f6−f×81=0
Use the commutative property to reorder the terms
6f6−81f=0
Factor the expression
3f(2f5−27)=0
Divide both sides
f(2f5−27)=0
Separate the equation into 2 possible cases
f=02f5−27=0
Solve the equation
More Steps
Evaluate
2f5−27=0
Move the constant to the right-hand side and change its sign
2f5=0+27
Removing 0 doesn't change the value,so remove it from the expression
2f5=27
Divide both sides
22f5=227
Divide the numbers
f5=227
Take the 5-th root on both sides of the equation
5f5=5227
