#4300000# in scientific notation is #4.3xx10^6#

Explanation:

In scientific notation a number is written as #axx10^n#, where #n# is an integer and #a# is a number which has just one digit to the left of decimal i.e. #1<=a<10#.

Hence to write #4300000# in scientific notation, we will have to move decimal six places to the left.

Hence #4300000# in scientific notation is #4.3xx10^6#

#4.3*10^6#

Explanation:

The key realization is that when we write numbers in scientific notation, we want one digit before the decimal point.

In our case, we must loop it #6# times to the left. The number of times we loop it is the exponent, and looping right makes it positive. Thus, we have

#4.3*10^6#

Hope this helps!
