Division, because the process is a lot shorter than using a fraction.
Answer is 2 1/2
Step by Step explanation
Answer:
x^3 + 1/x^3 = 488
Step-by-step explanation:
- x^2 + 1/x^2 = 62
- x^2 + 1/x^2 + 2 = 64
- ( adding 2 in both sides )
- (x + 1/x ) ^2 = 64
- x + 1/x = 8
now,
- ( x+ 1/x ) ^ 3 = 512
- x^3 + 1/x^3 + 3 × x × 1/x ( x + 1/x )
- x^3 + 1/x^3 + 3 ( 8 )
- ( since x + 1/x = 8 )
- x^3 + 1/x^3 + 24 = 512
- x^3 + 1/x^3 = 488
hence, we got x^3 + 1/x^3 = 488
answer: 8
i added all the numbers and divided them by how much numbers there are
Answer:
It is either A or B. I am not certain only because I do not know if your assignement is indicating that the underlined greater sign represents an open dot or a closed dot
