Answer 2

Answer:

The addition of 100 + 0.32 + 0.05 with correct significant figures gives 100

Explanation:

• Significant figures are the minimum number of digits that needs to be specified in scientific notation without losing accuracy
• Here in this question, we are provided with 3 numbers and we have to find its addition to correct significant figures

Step 1:

• To obtain the answer to the given question we must first need to count the number of significant figures in the numbers
• In 100 we have only 1 significant figure i.e. 1
• In 0.32 we have 2 significant figures i.e. 3 and 2
• In  0.05 we have only 1 significant figure i.e. 5

Step 2:

• Now the least number of significant figures we have is 1, so our final answer will contain only 1 significant figure
• Add the given digits in the normal way

        We get,

        100 + 0.32 +0.05 = 100.37

• Since we want a solution to one significant figure only so .37 will be removed and the final answer will be 100

Therefore the addition of given numbers to correct significant figures is 100
