Question
Solve the equation
x=310
Alternative Form
x≈2.154435
Evaluate
x2×2x−20=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
2x3−20=0
Move the constant to the right-hand side and change its sign
2x3=0+20
Removing 0 doesn't change the value,so remove it from the expression
2x3=20
Divide both sides
22x3=220
Divide the numbers
x3=220
