---------
f(1) = 3 + 10^1.5 + 1
----
f(1) = 4 + 31.62 = 35.62

Given that f(x) = x%5E3 + %2810x%29%5E1.5 + 1 find the value of f’(1).
---------------------------------------------------------------------------

f'(x) = 3%2Ax%5E2 + 1.5%2A%2810x%29%5E0.5%2A10.

f'(1) = 3 + 1.5%2Asqrt%2810%29%2A10 = 3 + 1.5%2A3.162%2A10 = 50.43.
