Question - 1: - The half-life of Radium-226 is 1590 years. If a sample contains 300 mg, how many mg will remain after 1000 years?

Question - 2: - f and g are functions from R to R.
Consider f(x) = 6x+2, g(x) = x^{8}.
then fog = _______ & gof = _______
&
Consider f(x) = \sqrt{x^2+3}, g(x) = x^2+2
then fog = _______ & gof = ________


I don't know how to solve first one & I got wrong answers in both questions of second one. So please tell me the answer as soon as possible.
