Question
Solve the equation
x≥0
Alternative Form
x∈[0,+∞)
Evaluate
x5=x5
Rewrite the expression
x5−x5=0
Separate the equation into 2 possible cases
x5−x5=0,x5≥0−x5−x5=0,x5<0

More Steps

Evaluate
x5−x5=0
Calculate
0=0
The statement is true for any value of x
x∈R
x∈R,x5≥0−x5−x5=0,x5<0
The only way a base raised to an odd power can be greater than or equal to 0 is if the base is greater than or equal to 0
x∈R,x≥0−x5−x5=0,x5<0

Evaluate
−x5−x5
Collect like terms by calculating the sum or difference of their coefficients
(−1−1)x5
Subtract the numbers
−2x5
−2x5=0
Change the signs on both sides of the equation
2x5=0
Rewrite the expression
x5=0
The only way a power can be 0 is when the base equals 0
x=0
x∈R,x≥0x=0,x5<0
The only way a base raised to an odd power can be less than 0 is if the base is less than 0
x∈R,x≥0x=0,x<0
Find the intersection
x≥0x=0,x<0
Find the intersection
