Answer
So, after writing 763 to 2 significant figures, we get 760.
Explanation
## Step1:To write a number to two significant figures, we keep the first two digits that carry meaningful contribution to its precision. Looking at the number 763, we note that the first two digits are 7 and 6. ## Step2:Writing to two significant figures implies maintaining the value in most nearest possible approximation of first two significant digits. ## Step3:The digit 3 should be changed to 0 instead because it's the third digit from left. But, it's also important to ensure the relative size in context. Reflecting this ponderation must assure keeping the value in hundreds as it is already there in given figure by replacing the value after two digits from left(without altering the actual estimation).### The formula for writing to significant figures:Keeping the most significant figures and rounding off after them.
