Question

a,35x34+35x86+65x75+65x45

b,3x25x8+4x37x6+2x38x12

Answer 1

35x34+35x86+65x75+65x45

=35x(34 + 86) + 65(75+45)

=35x120 + 65x120

=(35+65)x120

=100x120=12000

b)3x25x8+4x37x6+2x38x12

=24x25+24x37 + 24x38

=24x(25 + 37 + 38)

=24x100=2400

Answer 2

a) 35 x 34 + 35 x 86 + 65 x 75 + 65 x 45

= 35 x (34 + 86) + 65 x (75+45)

= 35 x 120 + 65 x 120

= (35+65) x 120

= 100 x 120 = 12000

b) 3 x 25 x 8 + 4 x 37 x 6 + 2 x 38 x 12

= 24 x 25 + 24 x 37 + 24 x 38

= 24 x (25 + 37 + 38)

= 24 x 100 = 2400

 

Answer 3

a,35x34+35x86+65x75+65x45

= 35.(34+86)+65.(75+45)

=35.120+65.120

=100.120=12000

B)3.25.8+4.37.6+2.38.12

= 24.25+24.37+24.38

=24.(25+37+38)

=24.100=2400
