Evaluate 3√-8. Use pencil and paper. Explain how you can check that your result is correct. Show your work.

?, the value does not exist because you can't square root a negative value.

Step-by-step explanation:

root 8 can be simplified but in this case, its negative so answer D.N.E.

= 3 x √-8

= D.N.E.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
