17. 31.2 X = 3.12 X 10
Notice the larger number has the smaller exponent

18. 31.2 X = 3.12 X 10
Using the same concept what exponent would go
beside the 10? x 10
Notice the larger number has the smaller exponent

21. (5.45 X 10 ) + (3.12 X 10 )

22. (5.45 X 10 ) + (3.12 X 10 )
31.2 X 10

23. (5.45 X 10 ) + (3.12 X 10 )
31.2 X 10

24. (5.45 X 10 ) + (3.12 X 10 )
31.2 X 10

25. (5.45 X 10 ) + (3.12 X 10 )
31.2 X 10

26. (2.67 X 10 ) - (4.2 X 10 )

27. (2.67 X 10 ) - (4.2 X 10 )

28. (2.67 X 10 ) - (4.2 X 10 )

29. (2.67 X 10 ) - (4.2 X 10 )
