how do I simplify radicals with fractional radicands?
ex. 7sqrt(2) + sqrt(50) - 2sqrt(18)
10sqrt(3/5) - 24sqrt(5/3)
3sqrt(2/9) + 1/2sqrt(32) + sqrt(9/8)
This is an exercise in recognizing numbers. When I look at the first problem what I see is that
In the second problem I would like the denominators to be squares so that I can rewrite the expression with no fractions under the square root symbol. I can do this if I write
For the third problem the key is 32 since 32 = 16 2, again a square times 2. Can you write each of the other two radicands as a square times 2? Penny
