Assuming x is your number, x * 10^n = x moved n decimal places.
When n is positive, move the decimal point n places to the right.
When n is negative, move the decimal point n places to the left.
When n is 0, do nothing.
Convert the mixed number to an improper fraction. Any fraction can be expressed as a decimal by dividing the denominator into the numerator.
If its a fraction such as 3/4 then divide the denominator into the numerator which as a decimal is 0.75 but if its a whole number such as 15 then simply add .0 to the end of it and so 15 as a decimal is 15.0
The binary value of the decimal number 57 (fifty seven) is 00111001According to three different decimal to binary converters I tried, the decimal number 57 is expressed in binary as 111001. Being able to convert to binary is important because binary is what computers work in.
To express the number 1100 as a decimal, you simply write it as 1100.0. This is because the decimal point is always placed at the end of a whole number to indicate that there are no fractions or parts of a whole. Therefore, 1100 as a decimal is written as 1100.0.
Decimal ( 41 ) = binary ( 1 0 1 0 0 1 )
Write the number as a decimal multiplied by a power of 10
You simply take the number of digits less one as the power, convert the number to a decimal between 0 and 10 and then note this decimal x 10 to the power calculated previously. e.g. 1,000,000 in scientific notation is 1.0 x 106 123,000,000 in scientific notation is 1.23 x 108
Scientific notation is used to express very large or very small numbers. instead of writing 15,000,000, you can express the same number by writing it as 1.5 * 107 or, you could express the very small number .00000015 as 1.5 * 10-7 to express a number in scientific notation, simply place a decimal point after the first number (in a large number) or before the last number (in a very small number) and multiply by ten to the nth power, where n is the number of digits following the decimal point (in a large number) or negate the number of digits before the decimal (in a very small number).
Scientific Notation is expressed by using a number, using an exponent as a number (usually a decimal) multiplied by a 10, and an exponent (the number on the exponent is the number of zeros the number has).Example: 120,000,000 in scientific notation is 1.2 X 107
Scientific notations do not care about the range of the number in question but do so about its precision. Therefore the notation for the given number will be - 7.53 X 102
from google :To write a number in scientific notation:Put the decimal after the first digit and drop the zeroes. In the number 123,000,000,000 The coefficient will be 1.23To find the exponent count the number of places from the decimal to the end of the number.In 123,000,000,000 there are 11 places. Therefore we write 123,000,000,000 as:
Scientific notation is a way of representing numbers, usually very large or very small, in the forma*10^b where 1
how to express scientific notation to a simle number
To write 180 in scientific notation, move the decimal point after the first digit, giving you 1.80. Then count the number of places you moved the decimal point. In this case, you moved it two places to the right. Finally, express the number 180 as 1.80 x 10^2 in scientific notation.
2.39873 X 10^12 Place decimal after first whole number and count decimal places from right to left until you reach that position. Count is the exponent.
It is not possible to express a number containing alphabetic characters (nA) in scientific form.
Scientific notation is the writing of a number as a decimal number with one digit left of the decimal and all the other digits to the right, and then the power of ten appropriate to expressing that number. Here we have 375,000 for our number. First we need to figure out where the decimal is going to be. It will, per the rule, be between the 3 and the 7. That puts it in a place where only the 3 is to the left of the decimal. (One digit, per the rule.) To get it there, we need to move the decimal to the left by five places. When we move the decimal to the left, we have to multiply by a positive power of 10 to correctly express the number. 375,000 = 3.75 x 105 for your answer in scientific notation.
