Evaluate the following.
15:5+3+4x6

15:32

Step-by-step explanation:

15:5+3+4×6

Using BODMAS rule

15:5+3+(4×6)

15:5+3+24

So add up

15:32

Since the two cannot be divided by the same number,we will have to leave the answer as

15:32

(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
