x5
32x5
32x5−12=0
Move the constant to the right-hand side and change its sign
32x5=0+12
Removing 0 doesn't change the value,so remove it from the expression
32x5=12
Divide both sides
3232x5=3212
Divide the numbers
x5=3212
Cancel out the common factor 4
x5=83
Take the 5-th root on both sides of the equation
5x5=583
