Which expression results in a product that is rational? (a)square root of 7 times square root of 10 (b)square root of 8 times square root of 10 (c) square root of 9 times square root of 10 (d)square root of 10 times square root of 10

C
The square root of 9+ the square root of 10=5.33483823

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
