Answer 1

54x 10 = 540

54x100 = 5400

54x1000 = 540 00

108x10 = 1080

108x100 = 10800

108x1000 = 108000

690x10 = 6900

690x100 = 69000

690x1000 = 690 000

Answer 2

54 x 10 = 540

54 x 100 = 5400

54 x 1000 =  54000

108 x 10 = 1080

108 x 100 = 10800

108 x 1000 = 108000

690 x 10 = 6900

690 x 100 = 69000

690  x 1000 = 690000

Answer 3

`54xx 10 = 540`

`54xx100 = 5400`

`54xx1000 = 540 00`

`108xx10 = 1080`

`108xx100 = 10800`

`108xx1000 = 108000`

`690xx10 = 6900`

`690xx100 = 69000`

`690xx1000 = 690 000`

  

Answer 4

`54xx 10=540`

`54xx100=5400`

`54xx1000=54000`

`108xx10=1080`

`108xx100=10800`

`108xx1000=108 000`

`690xx10=6900`

`690xx100=690 00`

`690xx1000 = 690 000`

Answer 5

54 x 10 = 540

54 x 100 = 5 400

54 x 1000 = 54 000

108 x 10 = 1 080

108 x 100 = 10800

108 x 1000 = 108 000

690 x 10 = 6900

690 x 100 = 69000

690 x 1000 = 690 000
