standard form

Question

how do you write 316.44 in standard form?

Answer 1

316.44 is already in standard form.

 

If you needed to convert it into scientific notation it would be: 3.1644 x 10². Scientific notation requires the first number to be greater than zero and less than 10--which is why the number is now 3.1644. Since 10² = 100 when you multiply 3.1644 by 100 it "moves" the decimal to the right two places, making the two numbers equal (representing the original number of 316.44)
