Evaluate `(25.2xx1374)/33.3`. All the digits in this expression are significant.

Text Solution

Verified by Experts

We have `(25.2xx1374)/33.3 = 1039.7838.`
Out of the three numbers given in the expression 25.2 and 33.3 have 3 significant digits and 1374 has our. The answer shold have three significnt digits. Rounding 1039-7838. to three significant digits, it becomes 1040. Thus, we write
`(25.2xx1374)/33.3 = 1040`
