00:00all right so i want to look at this cube root trick and that probably you don't know so here
00:07the simplest way of working it is by adding the numbers in the root sign
00:15and subtract 3 for me so here we have one plus two plus five so one plus two plus five
00:28this will give us eight so eight minus the three uh give us five and the cube roots of one
00:39two five is
00:40five that's five times five twenty five twenty five times five that's one two five so the same applies
00:47to this one now two plus one plus six so this is 39 so nine minor there right here i
00:59give us six
01:00six so two one six cube root of two one six is what six six six 36 36 by six
01:09two one six
01:11right then we have cube root of 343 so we have three plus four plus three so this is
01:26seven seven plus three that's ten so ten minus three give us seven so the answer is seven
01:36two i want you to solve this one
