50.1 x 10to the power of 3

Question

Is the number  written in Scientific notation. if not explain

Answer 1

If written exactly as shown, then no.  But 50.1 x 10³ would be correct scientific notation and that is probably what you were really asking about.   In normalized scientific notation, the first number is selected to have an absolute value between 1 and 10.  So, to write this number in normalized scientific notation, you would write 5.01 x 10⁴.  (We divide 50.1 by 10, so have to multiply 10³ by 10 which becomes 10⁴.)  Additionally, you could write 50.1E3 if using scientific E notation which is often used on calculators. And to cover all the bases, this number is 50,100.  (Write 50.1 as 50.100 and then move the decimal point 3 places to the right to reflect multiplication by 10³ which is 1,000.)  Hope that helps!

Answer 2

as written, this does not meet the requirements for scientific notation because the coefficient of 50.1 is larger than 10. to adjust this you want to move the decimal one additional spot to the left in order to have it written in proper scientific notation:

5.01 x 10^4
