Answer 1

The answer is A. 2,358

Answer 2

Answer : The correct option is, (A) 2358

Step by step explanation :

Significant figure : It is defined as the minimum number of digit us needed to express a number in scientific notation.

`15.11+(142* 16.5)`

`=15.11+2343`

Now we will add both the digits, we get

`=2358.11`

As per given expression, we conclude that the number of significant figure is 4. So, the answer will be, 2358

Hence, the correct option is, (A) 2358
