Question

When you are translating a number from scientific notation to standers form what does the exponent tell you a.the numbers of zeros to add to the number b.the number of places to move the decimal left c.same as b but right d.the number of times to multiply the first factor by itself

Answer 1

Here are two examples, you decide what I did.

3.45 x 10^7 = 34500000 , where was decimal and where is it now ?
5.632 x 10^-3 = 0.005632 , where was decimal and where is it now

did you notice that when the exponent on 10 is positive, the number is "big"
and when the exponent on 10 is negative, the number is "small"

Answer 2

1.234 x 10^3 = 1234
