I would say (I am abbreviating square root to sqrt)
1. 4 sqrt(8488) = 4 sqrt(2x2x2122) = 8 sqrt(2122)
2. 3 sqrt(6936) = 3 sqrt(6x34x34) = 102 sqrt (6)
3. 2 sqrt(8648) = 2 sqrt(2x2x2162) = 4 sqrt(2162)
Answer:
72.24
Step-by-step explanation:
Price for each camera = 14
Number of camera = 2dozen = 12 x 2 = 24
Total cp = 24 x 14 = 336
~~~~~~~~~~~~~~
Price for each camera= 10.99
Number of cams = 24
Total sp = 10.99 x 24 = 263.76
Loss = 336 - 263.76 = 72.24
