Answer:
360.
Explanation:
Step 1:
Combine and Determine sums of certain numbers: 12 = 22•3
(12)2 = (22•3)2 = 24 • 32 =
--5 • (24•32) /2
Step 2:
Simplify: 24•32) /2 =
--5 • 72
Step 3:
Multiply: 360
360
First, we need to solve the numbers in the parentheses.
(14-2)^2 = (14 - 2)(14 - 2) = 196 -56 +4 = 144 (Use FOIL)
Then, we multiply that by 5.
144 * 5 = 720
Finally, we divide by two to get our answer.
720 ÷ 2 = 360
