Question:

What is:

[tex]51+5^2.31+18^2-9.7[/tex]

Solution:

Consider the following expression:

[tex]51+5^2.31+18^2-9.7[/tex]

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

[tex]51\text{ + (25)(31)+(324)-(9)(7)}[/tex]

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

[tex]51\text{ +775+324-}63[/tex]

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

[tex](51\text{ +775+324)-}63[/tex]

that is:

[tex]1150-63[/tex]

Finally, we perform the respective subtraction:

[tex]1083[/tex]

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

[tex]1083[/tex]
