Scientific notation is a way to make these numbers easier to work with. Does scientific notation have to be between 1 and 10? The number of steps moved (n) is taken as the exponent. Record down the coefficient (a) and count the number of steps the decimal point was moved. To convert a number to scientific notation, place or move the decimal point of a number until the coefficient of the number is greater than 1 and less than 10. Therefore, it is written as 1.57821 x 10^5. What is the power of 10 when 157 821?Īnswer Expert Verified We write the number 157,821 by moving the decimal place to the left until the first number, taking note of the number of times you moved it. ![]() For example, 100 can be written as 10×10 = 102. The exponent tells you how many times ten is to be multiplied by iteslf to equal the number you wish to write. To make our job easier, we could put the time in scientific notation as well: (6.25 x 10 18 electrons per second) x (3.6 x 10 3 seconds) To multiply, we must take the two significant sets of digits (6.25 and 3.6) and multiply them together and we need to take the two powers-of-ten and multiply them together. In powers of ten notation, large numbers are written using ten to a power, or exponent. Numbers are written as a decimal number between one and 10 (including 1, but excluding 10) multiplied by some integral power of 10. Our power of 10 is going to be negative, just like in the last couple of this that we did.Scientific notation is commonly used in mathematics to represent positive or negative numbers that are extremely large or close to zero. Three feet were moving a decimal point to the right here. So we have one number in our decimal point and we could be right this as 3.24 times 10 to the negative. We have 0.3 to 4 feet and once again we're going to want to are Desperate Point. And that's our answer for part now, Part B. So we'll move it three, then another 36 in another 39 so that we can get our final result of 2.378 times 10 to the power of nine meters. So if you want to write it in power of 10 notation, let's move our decimal point so that we only have one number to the left of it. So we were decimal point right here at the very end, marked in red and technically it may have zeros extending for ever behind it since those don't contribute to the number. ![]() We want to convert some numbers into power of 10 invitation and let's start with this number here, which is two billion, 378 million. ![]()
