Answer 1

Answer:

$1) \: \: 34 \: and \: 57 \\ 2) \: total \: number = 64 \\ greatest \: number = 87 \\ smallest \: number = 10 \\ 3) \: total \: number = 9 \\ greatest \: number = 32 \\ smallest \: number = 10$

Step-by-step explanation:

$1) \: product \: of \: unit \: digit \: of \: numbers = 28 \\ = 2 \times 2 \times 7 \\ = 4 \times 7 \\ so \: one \: number \: unit \: place \: digit \: is \: 4 \: and \: other \: number \: unit \: place \: digit \: is \: 7 \\ product \: of \: ten \: place \: digit \: = 15 = 3 \times 5 \\ so \: pair \: numbers \: may \: be \: \\ 34 \: \: and \: \: 57 \\ or \\ 54 \: \: and \: \: 37 \\ but \: product \: of \: 54 \: and \: 37 \: is \: not \: equal \: to \: 1938 \\ so \: our \: answer \: is \: 34 \: and \: 57$

$2) \: given \: numbers \: are \:$

0,1,2,3,4,5,6,7,8

$total \:two \: digit \: numbers \: formed \: by \: these \: numbers \: \\ = 8 \times 8 = 64 \\ greatest \: number = 87 \\ smallest \: number = 10$

$3) \: given \: numbers \: are 0,1,2,3 \:$

$total \: number \: of \: two \: digit \: numbers \: formed \\ by \: given \: number \: without \: repitition = 3 \times 3 = 9 \\ greatest \: number = 32 \\ smallest \: number = 10$
