Answer 1

Answer:

The correct order is,

A, D, C, F, B, G

Step-by-step explanation:

Given subtraction problem,

A) $1.1\times 10^3-4.9\times 10^2$

Make both significant value with the same exponent of 10,

D) $1.1\times 10^3-\frac{10}{10}4.9\times 10^2$

By solving,

C) $1.1\times 10^3-0.49\times 10^3$    $(a^m.a^n=a^{m+n})$

Taking common $10^3$ from both terms,

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

Subtracting,

B) $0.61\times 10^3$

By solving,

G) $6.1\times 10^2$   ( $0.61 = 6.1\times 10^{-1}$ )
