Question

What is the sum of 5. 3*10^5 and 3. 8*10^4 in scientific notation.

Answer 1

Answer:

$5.86*10^{5}$

Explanation:

first you change the smaller number so that the 10 on both of them is power to the same number.

3.8*10^4  

here we will change this number so that it is 10^5 which mean will move the decimal point one digit to the left.

0.38*10^5

now we will add the two numbers while keeping  the 10^5.

5.3*10^5 + 0.38*10^5 = 5.68*10^5
