Question
Solve the equation
x=34
Alternative Form
x≈1.587401
Evaluate
x2×2x−8=0
Multiply
More Steps
Evaluate
x2×2x
Multiply the terms with the same base by adding their exponents
x2+1×2
Add the numbers
x3×2
Use the commutative property to reorder the terms
2x3
2x3−8=0
Move the constant to the right-hand side and change its sign
2x3=0+8
Removing 0 doesn't change the value,so remove it from the expression
2x3=8
Divide both sides
22x3=28
Divide the numbers
x3=28
