Answer:
b) 31 and c) 11
Explanation:
IMPORTANT: Order of operations is PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/SUbtraction).
B) Solve inside the parentheses first.
1. 2^3 - 6 = (2*2*2) - 6 = 2.
2. Now the equation looks like 3 + 7 (2)^2, Next we need to do exponents.
3. 2 to the power of 2 is 4, leaving you with 3+7(4)
4. Now multiply 7*4, which is 28 then add 3 to it.
So B) would ultimately be 31.
C) As we did in equation B, we start with parentheses.
1. (6/3) we can just simplify this to 2, so those parentheses are out of the way.
2. Now we need to do exponents, (-3)^2. This is the same as -3 * -3. This would equal 9.
3. So far the equation looks like 4 + 9 - 2 / 2.
4. Next would be to solve any multiplication/division problems we have. We can see from step 3 that we have a -2 divided by a positive 2. This would give us -1.
5. Now the equation looks like 4 + 9 - 2. Now you can just working from left to right.
So C) would solve to 11
