...maybe

Answer 6

Answer 7

Ok, well when you have \[\Large 4\sqrt{50}=4\sqrt{25*2}=4\sqrt{25}\sqrt{2}=4*5\sqrt{2}=20\sqrt{2}\]

Answer 8

the first attachment "idk2.jpg" i am clueless and the second attachment "confused.jpg" I would only go with A

Answer 9

That's where they messed up, they multiplied the 4 by the 25 instead of taking the square root of 25, thats how they got that 100 but thats not correct, you have to first take the sqrt of whatever your simplifying (in this case the 25 and 4 which are perfect squares) and simplify them down to 5 and 2 which are the sqrt's respectively, and then multiply that to the numbers just like I did up there

Answer 10

@doulikepiecauseidont & @mary.rojas thank you

Answer 11

your welcome good luck :)

Answer 12

Oh, well i CAN TELL YOU THAT \[\sqrt[3]{2^{4}}=\sqrt[3]{2^{2}\times 2^{2}}\] and that means they have common radicals so they can be combined, but in case you forget on a test, 3 of them say fals and one of them says true, so that would also be a good tip

Answer 13

And the second one doesn't have liek radicals so you know its D
