sqrt180 - sqrt125 + sqrt5
\[\huge\rm \sqrt{180}- \sqrt{125}+\sqrt{5}\] factor 125 and 180
16750 I believe
whoops did it wrong
16800 is the answer
what are factors of 125 ?
1,5,25,125

:-)
okay so factor of 125 are 1,5,25,125 we have to pick one number that should be perfect square
Ik sorry
it's okay :-)
125 is 5,5,5,. 180 is 3,3,2,2,5. Then you have for 180,an index of 6, radicand 5. 125 woollen index 5, radicand 5.
@Nnesha he/she answered
factor of 180 aare 1,2,3,4,5,6,9,10,12,15,18,20,30,36,45,60,90,180 we need greatest factor which should BE perfect square root (meaning not decimal)
yes right 125 = 5 times 5 times 5 so \[\huge\rm \sqrt{180}- \sqrt{5 \times 5^2}+\sqrt{5}\] square of 5 can cancel out with square root so we can write it outside the root so \[\huge\rm \sqrt{36 \times 5}- 5\sqrt{5 }+\sqrt{5}\] greatest factor of 180 is 36 36 times 5=180 take square root of 36 let me know what you get
