Best ResponseYou've already chosen the best response.0and on the second one until here: sqrt 5*9*n^2*n^2*n = sqrt 5 * sqrt 9 * sqrt n^2 * sqrt n^2 * sqrt n

Best ResponseYou've already chosen the best response.0the 1st question is simply \[\sqrt{7} \times \sqrt{14} + \sqrt{7} \times \sqrt{3} = \sqrt{ 7 \times 14} + \sqrt{7 \times 3}\] you need to simplify it the 2nd question \[\sqrt{45n^5} = \sqrt{9n^4 \times 5n} = \sqrt{9n^4} \times \sqrt{5n}\] just simplify

Best ResponseYou've already chosen the best response.0I just missed the sqrt 7x3 right?

Best ResponseYou've already chosen the best response.0going back to the 1st question \[\sqrt{7 \times 14} = \sqrt{98} = \sqrt{49 \times 2}\] which can be simplified.

Best ResponseYou've already chosen the best response.0well \[\sqrt{49} \times \sqrt{2} = 7\sqrt{2}\] so the 1st question is \[7\sqrt{2} + \sqrt{21}\] the 2nd question \[\sqrt{9n^4} \times \sqrt{5n} = 3n^2\sqrt{5n}\] hope this makes sense.
