I only see two numbers right there. Does that help?Bubofthedead said:
Significant figures are the digits in a number that are considered to be accurate and reliable. They represent the precision of a measurement or calculation, and are used to indicate the level of uncertainty in a value.
To determine the number of significant figures, start counting from the first non-zero digit and continue counting until the last digit. Zeros between two non-zero digits are also considered significant. However, trailing zeros after a decimal point are only significant if they are explicitly stated in the measurement or calculation.
To round a number to 2 significant figures, look at the third digit. If it is 5 or more, round the second digit up by 1. If it is less than 5, leave the second digit as it is. Then, remove all digits after the second digit.
Yes, scientific notation can be used in 2 significant figure problems. In fact, it is often used to express very large or very small numbers in a more convenient and concise way.
Some examples of 2 significant figure problems include measuring the length of an object with a ruler marked in millimeters, calculating the volume of a liquid using a graduated cylinder, and converting temperature from Celsius to Fahrenheit using a thermometer.
