Simplify. 7√50x^15y^21 assume x and y are nonnegative. a.5x7y102xy−−−√b.35x7y102xy2−−−−√c. 35x7y10xy−−√d.35x7y102xy−−−√

Given expression is where x and y are non negative.

Now we have to simplify this to find the correct matching choice.

Which best matches with choice D.

Hence final answer is .

(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

answer: the answer is 35%
