Explanation:
#(8x)^(1/2)+6=0#
Subtract
#(8x)^(1/2) = -6#
Square both sides, noting that squaring may introduce spurious solutions:
#8x = 36#
Divide both sides by
#x = 36/8 = 9/2#
Check:
#(8x)^(1/2)+6 = (8*9/2)^(1/2)+6 = 36^(1/2)+6 = 6+6 = 12#
So this
The problem is that while
So the original equation has no solutions (Real or Complex).
