WebThis value right over here is greater than or equal to 1, but it is less than or equal to 9. It's a digit between 1 and 9, including 1 and 9. And it's being multiplied by 10 to some power. So it looks like we're done. This simplified to 1.4 times 10 to the negative 2. WebWhen you calculate the product 1.8 × 2.01 × 1.542, you start with three written representations which you are supposed to assume are exact. Then you multiply the first two of them, and get a number which is exactly represented by the notation 3.78. Now, it's true that 3.8 is an approximate written representation of that number.
WebJul 1, 2024 · There are different methods which may be used to round numbers. The usual method is to round numbers with digits less than 5 down and numbers with digits greater than 5 up (some people round exactly 5 up and some round it down). Example: If you are subtracting 7.799 g - 6.25 g your calculation would yield 1.549 g. WebExpress the logarithm of 6.213 x 10-10 to the correct number of significant figures. log (6.21 3 x 10-10) = log (6.21 3 )+log (10-10) = 0.793 3 013536 + (-10) = -9.206 6 986464 → -9.206 …
