Radicals Tips 1. Make sure that one of the 2 factors of the radicand (expression under the radical) is the largest absolute squ ar: use: change 72 Correct 72 = 36 ? 2 = 62 Incorrect 72 = 9 ? 8 = 38 2. To be able to add or subtract radicals, the radicands must be the same. use 1: add on 32 + 52 Answer: Since radicands are the same, (3 + 5)2 = 82 physical exercise 2: Subtract 73 - 3 Answer: (7 1)3 = 63 Example 3: 318 - 52 (Must change early) 39 2 - 52 3 ? 3 ? 2 - 52 92 - 520 Answer: 42 Example 4: 780 + 5 716 ? 5 + 5 7 ? 45 + 5 285 +1 5 Answer: 295 3.
To cypher and divide radicals, perform the indicated operation on the radicands and then simplify: (You do not need radicand to be the same in pitch to multiply or divide) Example 1: (85) (42) = (8)(4) 5 2 = 3210 Example 2: (105) ÷ (25)= (10 ÷ 2) (5 ÷ 5) = 5 (1) = 5 Example 3: (320 ) (32) sometimes it is easier to simplify first (64 ? 5) (16 ? 2 (85) (42) Answer = 3210 ! Example 4: (6500) ÷ 220 ? revision as a fraction and divide = 6500220 = 325 = 3(5) Answer = 15 send - Simplify each of the following 1. 32 2. 640 3. -380 4. 362 - 62 +92 5. - 5 - 75 + 5 6. 12 + 27 7. 345 - 620 8. two hundred - 32 9. unwrap the quotient of 20 and 2 10.
