1.9\cdot10^3

Step-by-step explanation


1900

Calculating scientific notation for a positive integer is simple, as it always follows this notation:


a\cdot10^b

Step 1

To find a, take the number and move a decimal place to the right one position.

so


1900\Rightarrow1.900\text{ }

Step 2

Now, to find b, count how many places to the right of the decimal.


1900\Rightarrow1.900\text{ ( 3 places)}

Step 3

finally,

Building upon what we know above,

a= 1.9

b=3 (Since we moved the decimal to the left the exponent b is positive)

replace


\begin{gathered} a\cdot10^b \\ a\cdot10^b=1.9\cdot10^3 \end{gathered}

therefore, the answer i


1.9\cdot10^3

I hope this helps you
