If you square 3, you get 9, and if you "take the square root of 9", you get 3
Answer:
-1
Step-by-step explanation:
All negative integers are not whole numbers
PB = 12 (P=1, B=2) Numerical values are assigned to each letter and each letter takes on a single number.
Let u = x.lnx, , w= x and t = lnx; w' =1 ; t' = 1/x
f(x) = e^(x.lnx) ; f(u) = e^(u); f'(u) = u'.e^(u)
let' find the derivative u' of u
u = w.t
u'= w't + t'w; u' = lnx + x/x = lnx+1
u' = x+1 and f'(u) = ln(x+1).e^(xlnx)
finally the derivative of f(x) =ln(x+1).e^(x.lnx) + 2x
