(1) (radical number 2+ radical number 10)× radical number 2= radical number 4+ radical number 20 = 2+ radical number 5.

(2) (root number 3+2 root number 5)? =3+3* radical number 3*2 radical number 5+20=23+6 radical number 15

(3) (radical number 2+ radical number 3) (radical number 3-3 radical number 2) = square root of 26-6+square root of 6-36 = square root of-6.

(4) (radical x+ radical y) (radical x- radical y) = (radical x) square-(radical y) square =4X-Y

(5) (root number 3+ root number 2)? -(root number 3- root number 2)? = (radical number 3+ radical number 2+ radical number 3- radical number 2) (radical number 3+ radical number 2- radical number 3+ radical number 2) = radical number 3*2 = the square root of 46.

(6)(2 roots 12-4 roots 1/8+3 roots 48)×3 roots 2

=6 roots 24- 12 roots (1/4)+9 roots 96

The square root of = 12 6 -6+36 6 = 48 6-6.

(7) The number of roots of 3+the number of roots of 2/the square root of kloc-0/2-6) and the number of roots of a period 12.

= root number (3/ 12)+2 root number (12/ 12)- root number (6/ 12)

= 1/2+2- root number 2/2

=3/2- radical sign 2/2

(8)(4 radicals 2- 8) Geng radicals 2+ (radicals 3+ radicals 1/3) Geng radicals 3

=4 roots (2/2)- 8/2 roots+3/3 roots+3 roots (1/9)

=4-2+ 1+ 1=4
