Question
Solve the inequality
Solve the inequality by testing the values in the interval
Solve the inequality by separating into cases
t∈(−∞,0)∪(34,+∞)
Evaluate
2t×8<4t4
Multiply the terms
16t<4t4
Move the expression to the left side
16t−4t4<0
Rewrite the expression
16t−4t4=0
Factor the expression
4t(4−t3)=0
Divide both sides
t(4−t3)=0
Separate the equation into 2 possible cases
t=04−t3=0
Solve the equation
More Steps

Evaluate
4−t3=0
Move the constant to the right-hand side and change its sign
−t3=0−4
Removing 0 doesn't change the value,so remove it from the expression
−t3=−4
Change the signs on both sides of the equation
t3=4
Take the 3-th root on both sides of the equation
3t3=34
Calculate
t=34
t=0t=34
Determine the test intervals using the critical values
t<00<t<34t>34
Choose a value form each interval
t1=−1t2=1t3=3
To determine if t<0 is the solution to the inequality,test if the chosen value t=−1 satisfies the initial inequality
