We need to first consider the base case, n=0. (We consider the smallest possible value of n as the base case.)7^(80+3) + 2 = 343 + 2 = 345 = 69 * 5, so the statement is true for n=0.Assume true ...
Tree diagramP(Head then tail) = p(1-p)=6/25Solve above equationp=2/5 as heads are more likely than tails.
This is a separable differential equation, so the first step is to separate the two variables. Factorise out the x from the top bracket so that the equation becomes: dy/dx = x(y^2+1)/yThe next step is to ...
First I would look for common factors in either the numerator or the denominator. The denominator has the common factor of (2x) so i would factorise it by 2x in order to give (3x2-8x-3)/(2x)(x-...
