Question
Solve the equation
z=34
Alternative Form
z≈1.587401
Evaluate
z2×2z−8=0
Multiply
More Steps
Evaluate
z2×2z
Multiply the terms with the same base by adding their exponents
z2+1×2
Add the numbers
z3×2
Use the commutative property to reorder the terms
2z3
2z3−8=0
Move the constant to the right-hand side and change its sign
2z3=0+8
Removing 0 doesn't change the value,so remove it from the expression
2z3=8
Divide both sides
22z3=28
Divide the numbers
z3=28
Divide the numbers

Calculate
4
z3=4
Take the 3-th root on both sides of the equation
3z3=34
Solution
z=34
