Calculate and indicate the answer:
Previously mentioned in the order of operations that exponents come before multiplication and division which come before addition and subtraction (and parentheses always come before everything),
Let's calculate then first the value of the expression inside the parentheses (by calculating the roots inside the parentheses first) :
where in the second stage we simplified the expression in parentheses,
Next we'll calculate the values of the terms with exponents:
then we'll calculate the results of the multiplications
and after that we'll perform the subtraction:
Therefore the correct answer is answer B.

\( 5+\sqrt{36}-1= \)
Because of PEMDAS order! The square roots are inside parentheses, so you must calculate them first: and , giving you .
asks "what number times itself equals 9?" while means "9 times 9". They're opposite operations!
Yes, but for perfect squares like 4, 9, 16, 25, try to memorize them! It makes these problems much faster and builds your number sense.
You probably calculated first, getting 16, then tried to work with the square roots. Always follow PEMDAS - parentheses come before exponents!
Use PEMDAS: Please Excuse My Dear Aunt Sally. Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right).
If it's not a perfect square, leave it as a square root or use a calculator. But in this problem, both and simplify to whole numbers!
