Question

reduceti termenii asemenea a)√2x+√3y-√8x+√27y
b)√18x-√20a-3√2x+2√5a+5a
c)4√3x-√12x+2√75x va rog dau coroana!

Answer 1

a)√2x+√3y-√8x+√27y = √2x+√3y -2√2x+3√3y = √2x+4√3y -2√2x

b)√18x-√20a-3√2x+2√5a+5a = 3√2x - √20a -3√2x +2√5a + 5a =
= -2√5a +2√5a +5a = 5a

c) 4√3x-√12x+2√75x  = 4√3x -2√3x +2*5√3x = 4√3x -2√3x + 10√3x = 12√3x

Answer 2

A) = radical 2x + radical3y- 2radical2x + 3radicaly
=> 4radicaly- radical2x
B))
3radical2x - 2radical5a -3radical2x + 2radical5a+ 5a =
=> 5a
C))
4radical3x - 2radical3x +10radical3x =
=> 12radical 3x
