Question

What is the solution to the problem expressed to the correct number of significant figures? 15.11 + (142 × 16.5) =

Answer 1

2,360

Step-by-step explanation:

This is correct! :)

Answer 2

Hello!

The solution is 2360

Why?

This problem can be solved using the PEMDAS rule, which tells you the order in which operations should be carried out.

1. Parenthesis
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Substraction

For the given problem, the number of significant figures will be 3 (the number of significant figures in 142 and 16.5, the values with the least amount), so all values need to be converted first to 3 significant figures:

`15.1+(142*16.5)`

Then, we can proceed solving the problem:

`15.1+(142*16.5)=15.1+(2343\approx2340)=2355,1\approx2360`

Have a nice day!
