We need to first move the decimal two (2) places to the left:
480 = 4.80 x 102
The 2 in 102 comes from how many places we moved the decimal. It's positive because the number it represents is larger (480 > 4.8)
With one significant figure, we need to round to the nearest whole number:
5 x 102
The answer is 5 x 102
0.0357 has three significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
The number of significant figures in 0.0004 L is 1. In scientific notation, trailing zeros to the right of the decimal point are considered significant. Therefore, in this case, only the non-zero digit (4) is significant.
1000 is written with one significant figure, with only the 1 being a significant figure.
15 000 894 written with 5 significant figures is 15 001 000, as the 894 rounds up to the nearest significant figure. 1.5001*10^7
It has 1 significant figure.
As a product of its prime factors in exponents: 218 = 262144
The exponential form of 480 with one significant figure is (4.8 \times 10^2). In this representation, the number is expressed in a way that highlights the most significant digit, which is 4, while the rest of the digits are adjusted accordingly.
6.21 with one significant figure is just 6
50
I DONT FREAKING KNOW BRO
The answer is 6*10^5 g.
To express 0.00628 to one significant figure, we focus on the first non-zero digit, which is 6. Thus, 0.00628 rounded to one significant figure is 0.006.
To express 273 to one significant figure, you round it to the nearest ten. The first significant figure is 2, and since the digit following it (7) is 5 or greater, you round up. Therefore, 273 to one significant figure is 300.
The number 27000000 expressed using 1 significant figure is 3 x 10^7.
(if there is to be one significant figure) 2 * 102(if there are to be two significant figures) 2.0 * 102 (if there are to be three significant figures) 2.00 * 102
The quantity of 400 m has one significant figure unless specified otherwise. If it is written as 400. or in scientific notation (e.g., 4.00 × 10²), it would indicate three significant figures. Without additional notation, the trailing zeros in 400 are not considered significant. Therefore, it is typically interpreted as having one significant figure.
To three significant figure, 483.54 becomes 484. The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". Expressed in Scientific Notation, 484 becomes 4.84 x 102.
