Is 1.58 the same as 1.588235294 in scientific notation?

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.


How do you convert scientific notation to decimal notation?

If the number in sci. notation has a positive exponent, move the decimal to the right the same number of spaces as the exponent's number. For example: 5.78 x 103 = 5780 If the exponent is negative, move the decimal to the left the same number of spaces as the exponent's number. For example: 2.945 x 10-5 = 0.00002945

The number 5974000000000000000000000 in scientific notation is 5.974 x 10^24. This is because scientific notation represents a number as a coefficient multiplied by 10 raised to a certain power. In this case, we move the decimal point 24 places to the left to convert the original number into scientific notation.
