Answer:
[tex]1.1\times 10^3-4.9\times 10^2=6.1\cdot 10^2[/tex]
Step-by-step explanation:
Given : Expression [tex]1.1\times 10^3-4.9\times 10^2[/tex]
To find : Arrange the steps in correct order to perform this subtraction problem ?
Solution :
Step 1 - Write the expression,
[tex]1.1\times 10^3-4.9\times 10^2[/tex]
Step 2 - Multiply and divide by 10,
[tex]1.1\times 10^3-4.9\times \frac{10}{10}\times 10^2[/tex]
Step 3 - Solve the exponent,
[tex]1.1\times 10^3-0.49\times 10^3[/tex]
Step 4 - Taking common term,
[tex](1.1-0.49)\cdot 10^3[/tex]
Step 5 - Subtract the bracket,
[tex]0.61\cdot 10^3[/tex]
Step 6 - Multiply and divide by 10 to convert into scientific form,
[tex]\frac{10}{10}\cdot 0.61\cdot 10^3[/tex]
Step 7 - Write in proper form,
[tex]6.1\cdot 10^2[/tex]
Therefore, [tex]1.1\times 10^3-4.9\times 10^2=6.1\cdot 10^2[/tex]
