Standard form: 8.85x10^6= 8 850 000 (move six times to the right for find the number)
................................................->->->->.
Ex 2. How heavy is an elephant? is a 2.4x10^2= 240 lb. (two hundred forty pounds)

Standard form: 2.4x10^2= 2 40 (move two times to the right for find the number)

Or doing the same but using negative numbers for find a smallest number.

Ex. How heavy is an ant? is a 6.5x10^-5= .000065
