Sir, the first product is not in standard form. The product u wrote 19.1513*10^11 But in std scientific form if the decimal part is more than 10 then we shall have to give it a form that is less than 10 So the product will be 1.91513*10^12 [ we moved the decimal point one place left and it means we divide it with 10 and to neutralize it simultaneously we multiply with 10 Hence the power of 10 becomes 12 Comment please
You're right Sir, is just that you can still shift the decimal point, thanks for the observation please follow my channel on Facebook and Tiktok on "Pambegua online maths class".
