Best ResponseYou've already chosen the best response.0So, the same applies as with your previous question. Try coming up with the answer based on that and post it, then we'll see if it's right, and if it's wrong I'll explain the process again.

Best ResponseYou've already chosen the best response.0So if you have any negative number a, that's the same as saying 1 * a. Above, we have 75. That's the same as 1 * 75. Finally, \(\sqrt{1} = i\).

Best ResponseYou've already chosen the best response.0Not quite. Since we know 1 * 75 = 75, we get: \[\sqrt{1 * 75}\] \[\sqrt{1}\sqrt{75}\] What's \(\sqrt{1}\) again?

Best ResponseYou've already chosen the best response.0Yep, that's part 2, factoring out the 75 into 25 * 3 and doing that goodness :)
