If a= 10.5 and b= 2.01 , considering significant digits write the value of a +b .

Text Solution

Verified by Experts

`a + b = 10. 5 + 0.01 = 12.51 `
The number of significant digits on the right side of the decimal point of a = 1 and it is less than that of b . So their sum will contain one significant digit on the the right side of the decimal point .
So considering significant digits , a+ b = 12.5
