**RadicalsRoots of Real Numbers (section 7.4)**Target Goals: Simplify radicals having various indices Use a calculator to estimate roots of numbers**Radicals not just square roots!**Radical Sign Index Radicand (the number under the radical sign)**Ex 3) Find the following using your calculator:**Calculator Tips: For cubed roots/index = 3 “MATH” button, option “4” For indices larger than 3 * On the home screen, press the index # * “MATH” button, option “5”**Directions**• You will be presented with a problem to work on individually. • Try to not use your notes. • If you get the question correct, that will correspond to a homework problem that you will NOT be required to do. • Keep track of the homework problems you are NOT required to do.**1. Simplify:**10**If you got #1 right, you don’t have to do #13 on your**homework**2. Simplify:**10**If you got #2 right, you don’t have to do #15 on your**homework**3. Simplify:**10**If you got #3 right, you don’t have to do #19 on your**homework**4. Simplify:**10**If you got #4 right, you don’t have to do #21 on your**homework**5. Simplify:**• Not possible 10**If you got #5 right, you don’t have to do #29 on your**homework**6. Simplify:**10**If you got #6 right, you don’t have to do #35 on your**homework
