log4(x-3)=2 4^2=x-3 16=x-3 19=x Does this mean the solution would be x=19 or no solution? How would I check this to know if 19 is a solution. I know I plug it back in. Like so: log4(19-3)=2 4^2=19-3 16=16 Did i check correctly?

why does the equation x^2=-9 has no real solution? This I can't figure out. why does the equation x^2 = 9 has two solutions? Is it because it satisfied by both 3 and -3 so it has two solutions.
