Best ResponseYou've already chosen the best response.2look at the problem this way \[\sqrt{5 \times 25 \times h^2 \times h^2}\] which terms can you take the square root of..?

Best ResponseYou've already chosen the best response.025 would be 5 and wouldn't h^2 and h^2 be crossed out? still new to this

Best ResponseYou've already chosen the best response.2well 25 to 5 is correct h^2 goes to h when you take the square root so the problem can be rewritten as \[\sqrt{5} \times \sqrt{25} \times \sqrt{h^2} \times \sqrt{h^2} = \sqrt{5} \times 5 \times h \times h\] just simplify it

Best ResponseYou've already chosen the best response.2well it has been simplified now... all you need to do is tidy up the answer so it matches one of your choices

Best ResponseYou've already chosen the best response.0and how would you go about doing this?

Best ResponseYou've already chosen the best response.2ok... in bits \[\sqrt{5} \times 5 = 5 \sqrt{5}\] what does \[h \times h =\]

Best ResponseYou've already chosen the best response.2h^2 is correct so its now \[5 \times \sqrt{5} \times h^2 = 5 \times h^2 \times \sqrt{5}\] rememeber when muliplying, the order doesn't matter

Best ResponseYou've already chosen the best response.0can you square root 5 though is that even possible?

Best ResponseYou've already chosen the best response.2ok... the solution in correct but in algebra will normally don't write the multiplication signs when writing a term... so how can you rewrite \[5 \times h^2 \times \sqrt{5}\]

Best ResponseYou've already chosen the best response.0so wouldn't the answer be 5h^2√5?

Best ResponseYou've already chosen the best response.2just write it without the multiplication signs

Best ResponseYou've already chosen the best response.0\( \sqrt{5} \) is theoretically possible... but it is not a "nice" number 2.236067977499789696409173668731276235440618359611525724270897245410520925637804899414414408378782275... it goes on forever (ugh!)
