(b) 286
(c) 48
(d) 64​

Answer 1

$29 \times 48 = \\ 2 \times 9 \times 4 \times 8 = 576 \\ \\ 3 5 \times 16 = \\ 3 \times 5 \times 1 \times 6 = 90 \\ \\ 22 \times 46 = \\ 2 \times 2 \times 4 \times 6 = 96 \\ \\ therefore \\ 42 \times 17 = \\ 4 \times 2 \times 1 \times 7 = 56$

hope it helps you.....
