A math problem. In the practice part of the eighth grade last semester. √ indicates the radical numbers √12+3 √1-5 and 1-2√48.
Root number 12+3* root number 4/3- root number 16/3-2/3*4 root number 3

=2 roots 3+2 roots 3-4/3 roots 3-8/3 roots 3

=0

√6 /4-(-3/4* √27/2 +3* √ 1/6)

= 1/4*√6+3/4*3/2*√6- 1/2√6

=( 1/4+9/8- 1/2)*√6=7/8*√6
