Answer 2

Answer:

$1.1\times 10^3-4.9\times 10^2=6.1\cdot 10^2$

Step-by-step explanation:

Given : Expression  $1.1\times 10^3-4.9\times 10^2$

To find : Arrange the steps in correct order to perform this subtraction problem ?

Solution :

Step 1 - Write the expression,

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

Step 2 - Multiply and divide by 10,

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

Step 3 - Solve the exponent,

$1.1\times 10^3-0.49\times 10^3$    

Step 4 - Taking common term,

$(1.1-0.49)\cdot 10^3$    

Step 5 - Subtract the bracket,

$0.61\cdot 10^3$  

Step 6 - Multiply and divide by 10 to convert into scientific form,

$\frac{10}{10}\cdot 0.61\cdot 10^3$

Step 7 - Write in proper form,

$6.1\cdot 10^2$

Therefore, $1.1\times 10^3-4.9\times 10^2=6.1\cdot 10^2$
