Question

If a=9+2root6 and b=57/a,then what will be the value of a square+b square.

Answer 1

Step-by-step explanation:

a²=(9+2 root6)^2

=81+4x6

=81+24

=105

a²+b²=105+(57/105)²

=105+(19/35)²

=105+(361/1225)

=(105x1225+361)/1225

=105.29

Answer 2

Answer:

a²=(9+2 root6)^2

=81+4x6

=81+24

=105

a²+b²=105+(57/105)²

=105+(19/35)²

=105+(361/1225)

=(105x1225+361)/1225
