Question

1. Express 0.00456 in standard form.

Answer 1

Answer: 4.56 x 10^-3

Step-by-step explanation: To convert scientific notation to standard form, all you have to do is move the decimal to the left or the right until you get a number that is more than 1 and less than 10, then count however many spaces you had to move and add that as your exponent over 10 (if you move left, the exponent is positive, and right is negative). Basically, this just lets you know that the actual number is that many times smaller or larger than the number in your answer.

Answer 2

Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.
