Answer:
19. 1 do 4^5 which is 1024 then do 1024^0 which is 1
21. 0.000064 do 5^-2 which is 0.04 then do 0.04^3 which is 0.000064
23. 2.33 do 9^4 which is 6561 then do 6561^-2 which is 2.32305731 so you round it to 2.33
btw you should talk to me more
The line 
is already written in the 
form. This means that 
is the slope. If two lines are perpendicular, their slopes are the anti-inverse of each other, i.e. their product is -1.
So, our perpendicular line has a slope of 
Finally, we want a line passing through (1,1) with slope :
You multiply both of the equations until you have two of the same term the same like for example, say I have 4x and 5x. You want to multiply until both have the same number, so multiply 5x by four, then multiply 4x by five, and you will get 20x, then both of those cancel out and you will be left with the other variable, and you just solve like a normal equation.
