Question

48*4*2+42*8+5*16

Answer 1

C1:  48 x 4 x 2 + 42 x 8 + 5 x 16

=     384      +   336   +  80

=         720                + 80

=                   800

 C2: 48 x 4 x 2 + 42 x 8 + 5 x 16

= 48 x 8      +  42 x 8 + 5 x 2 x 8

= 48 x 8      +  42 x 8 + 10 x 8

=       ( 48 + 42 + 10 ) x 8

=            100              x 8

=                  800

Answer 2

48 x 4 x 2 + 42 x 8 + 5 x 16

= 48 x 8 + 42 x 8 + 10 x 8

= 8 x (48 + 42 + 10)

= 8 x 100

= 8000

Answer 3

\(42\cdot4\cdot2+42\cdot8+5\cdot16\)

\(=42\cdot8+42\cdot8+5\cdot2\cdot8\)

\(=42\cdot8+42\cdot8+10\cdot8\)

\(=8\cdot\left(42+42+10\right)\)

\(=8\cdot94\)

\(=752\)
