please help with question 5 & 6

5. Civen the following complexity categories, rank their degree of complexity by marking each eategory with a number (fiom 1 to 8 ). (hint see properties of Order) 6. Civen the following functions, determine the membership of each by marking the set, O(n2),(n2), or (n2) on its right hand side. For example, n lg n+n O(n2), you mark O(n2) on the right of function nlgn+n. Note that each function may belong to more than one set. nlgn6x2+5n29+n2100n+10007n3+5n10x2+6nlgn
