Is 1.58 the same as 1.588235294 in scientific notation?

Answer 1

No, scientific notation is when you express a number as a multiple of a power of ten.

1.58 would be rounding the number not changing it to scientific notation. To change 1.588235294 to scientific notation, you multiply 1.588235294 by a multiple of 10 to move the decimal point to the right until there is one number to the right of the decimal point..

So 1.588235294 * 100000000 = 158823529.4

Then you express 100000000 as an exponent. 100000000 = 10^7.

BUT!!! Because to change 158823529.4 back into 1.588235294, you would have to divide it by 10^7, you have to change it to a negative exponent so 10^-7.

The final answer is 158823529.4*10^-7 which is the same as 158823529.4/10^7 or 158823529.4/100000000.
