Question

Arrange the steps in the correct order to perform this subtraction problem. 1.1 × 10^3 – 4.9 × 10^2 PUT THESE IN ORDER please A)1.1*10^3-4.9*10^2 B)0.61*10^3 C)1.1*10^3-0.49*10^3 D)1.1*10^3-10/10*4.9*10^2 E)10/10*0.61*10^3 F)(1.1-0.49)*10^3 G)6.1*10^2

Answer 1

1=1.1 x 10^3 - 4.9 x 10^2

2=1.1 x 10^3 -10/10 x 4.9 x 10^2

3=1.1 x 10^3 -0.49 x 10^3

4= (1.1 -0.49) x 10^3

5=0.61 x 10^3

6=10/10 x 0.61 x 10^3

7= 6.1 x 10^2

Explanation:

i got it right

Answer 2

The correct order is,

A, D, C, F, B, G

Explanation:

Given subtraction problem,

A)
`1.1* 10^3-4.9* 10^2`

Make both significant value with the same exponent of 10,

D)
`1.1* 10^3-(10)/(10)4.9* 10^2`

By solving,

C)
`1.1* 10^3-0.49* 10^3`
`(a^m.a^n=a^(m+n))`

Taking common
`10^3` from both terms,

F)
`(1.1-0.49)10^3`

Subtracting,

B)
`0.61* 10^3`

By solving,

G)
`6.1* 10^2` (
`0.61 = 6.1* 10^(-1)` )
