The numbers are -4+2*sq rt of 3 and -4-2*sq rt of 3
sq rt (-2) + (sq rt 3))2 + (-2)2= i(sq rt 2) + 7 = 7 + i(sq rt 2) answerthis is a complex number, it cannot be further simplified.
The numbers are: -2 +2*sq rt 19 and -2 -2*sq rt 19 Check: (-2 +2*sq rt 19)*(-2 -2*sq rt 19) = -72 and (-2 +2*sq rt 19)+(-2 -2*sq rt 19) = -4
It is a rectangle and has sides of 3+sq rt of 3 and 3-sq rt of 3
The numbers are: 3-sq rt of 3 and 3+sq rt of 3

It is: (-2--2)2+(3--7)2 = 100 and the sq rt of this is the distance which is 10 units.

The lengths of the sides of the triangle are: 2*sq rt of 10, 5*sq rt of 2 and sq rt of 10 The 3 sides added together equals the perimeter which works out as 3* sq rt of 10 plus 5*sq rt of 2 in surd form
32x8= what
The numbers are: 8-4*sq rt of 3 and 8+4*sq rt of 3
If it is: 81/4 times sq rt of 3 Then it could be: 20.25 times sq rt of 3
