Differentiating exponential functions in exercise, find the derivative of the function. see example 2 and 3.
g(x) = e^ (x)1/2

Answer

g(x) = e^ (x)^1/2

Derivate with respect to x

g'(x) = (1/2 -1)*x^(1/2 -1) * e^ (x)^1/2

g'(x) = (-1/2)*x^(-1/2) * e^ (x)^1/2

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

i believe the correct answer is b.
