Solve the equation
a=321
Alternative Form
a≈2.758924
Evaluate
3a2×a−63=0
Multiply
More Steps
Evaluate
3a2×a
Multiply the terms with the same base by adding their exponents
3a2+1
Add the numbers
3a3
3a3−63=0
Move the constant to the right-hand side and change its sign
3a3=0+63
Removing 0 doesn't change the value,so remove it from the expression
3a3=63
Divide both sides
33a3=363
Divide the numbers
a3=363
Divide the numbers

Evaluate
363
Reduce the numbers
121
Calculate
21
a3=21
Take the 3-th root on both sides of the equation
3a3=321
