Question

Упростить выражение:
1) 2√27n-4√75n-3√12n
2) √60-3√375+6√35-2√735

Answer 1

1) 2/27n - 4/75n - 3/12n = 2/3*3*3*n -
- 4/5*5*3n - 3/2*2*3n = 2*3/3n - 4*5/3n - -3*2/3n = 6/3n - 20/3n - 6/3n = -17/3n
2) /60 - 3/375 + 6/35 - 2/735 =
/2*2*3*5 - 3/3*5*5*5 + 6/5*7 - 2/3*5*7*7 =
2/15 - 15/15 + 6/35 - 14/15 = -27/15 + 6/35
