Answer 1

36 . 23 + 62 . 23 + 46

= 23 (36 + 62) + 46

= 23 . 98 + 48

= 20 . 90 + 3 . 8 + 48

= 180 + 24 + 48

= 180 +(24 + 48)

= 180 + 72

= 252

Answer 2

\(36\cdot23\cdot62\cdot23+46\)

\(=36\cdot23+62\cdot23+23\cdot2\)

\(=23\left(36+62+2\right)\)

\(23\cdot100=2300\)

Answer 3

36 x 23 + 62 x 23 + 46

= 23 ( 62 + 36 ) + 46

= 23 x 98 + 46

= 2254 + 46

= 2300

Answer 4

23 x ( 36 + 62 + 2 )

= 23 x 100

= 2300

Answer 5

36 . 23 + 62 . 23 + 46

= 36. 23+ 62 .23 + 23 . 2

=23 . (36 +62 + 2 )

=23. 100

 = 2300

Answer 6

\(36\cdot23+62\cdot23+46\)

\(=36\cdot23+62\cdot23+2\cdot23\)

\(=\left(36+62+2\right)\cdot23\)

\(=100\cdot23=2300\)
