t=01−28t3=0
Solve the equation
More Steps

Evaluate
1−28t3=0
Move the constant to the right-hand side and change its sign
−28t3=0−1
Removing 0 doesn't change the value,so remove it from the expression
−28t3=−1
Change the signs on both sides of the equation
28t3=1
Divide both sides
2828t3=281
Divide the numbers
t3=281
Take the 3-th root on both sides of the equation
3t3=3281
