Remember that according to the order of operations, exponents precede multiplication and division, which precede addition and subtraction (and parentheses always precede everything).
So first calculate the values of the terms in the power and then subtract between the results:
Therefore, the correct answer is option B.
36
\( 11^2= \)
Because means "3 squared plus 3 cubed", not "3 to the power of (2+3)". These are completely different operations! You must calculate each power separately first.
(3 multiplied by itself once), while (3 multiplied by itself twice). The exponent tells you how many times to use 3 as a factor.
Use PEMDAS: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. For this problem, exponents come before addition, so calculate and first!
That's a common error! means 3 times 3, not 3 times 2. The exponent tells you how many 3's to multiply together, not what to multiply 3 by.
Yes, but enter it correctly! Type 3^2 + 3^3 or use parentheses. Most calculators follow order of operations automatically and will give you 36.
Work backwards: if your answer is 36, break it down. Does 36 = 9 + 27? Yes! Do 9 and 27 equal and ? Check: 3×3=9 ✓ and 3×3×3=27 ✓
