Answer 1

Question:

What is:

`51+5^2.31+18^2-9.7`

Solution:

Consider the following expression:

`51+5^2.31+18^2-9.7`

By precedence in arithmetic operations, we will first perform the powers:

`51\text{ + (25)(31)+(324)-(9)(7)}`

now, by precedence in arithmetic operations, we will perform the multiplications:

`51\text{ +775+324-}63`

now, by precedence in arithmetic operations, we will perform the sums:

`(51\text{ +775+324)-}63`

that is:

`1150-63`

Finally, we perform the respective subtraction:

`1083`

so that, we can conclude that the correct answer is:

`1083`
