Rationalise the denominator and simplify Is that $\frac{1}{2\sqrt{7}} + 2\sqrt{3} - \frac{1}{3\sqrt{7}} + \sqrt{3}$ or $\frac{1}{2} \sqrt{7} + 2\sqrt{3} - \frac{1}{3} \sqrt{7} + \sqrt{3}$ ? I'll assume its the first one since we are supposed to rationalise a denominator. $\frac{1}{2\sqrt{7}} + 2\sqrt{3} - \frac{1}{3\sq...

Math Help Let $a_{1}=\frac{5}{2}$ and $a_{n+1}=\sqrt{ a_{n}^{3} -12a_{n}+\frac{20n+21}{n+1}}$ Prove that the sequence $(a_{n})$ converges and find its limit A different approach: IF that sequence converges, then, calling the limit L, we must have lim a_{n+1}= \SQRT{lim(a_n^3)- 12lim(a_n)+ lim((20n+ 1)/(n+1))} which g...

How to figure out answer to logarithm First, of course, x= 0 is not a solution because log(0) is not defined. So you can divide both sides by x to get log(x)= 0.1 x. You can now write this as [itex]x= e^{0.1x}[/itex]. If you let y= -0.1x, that becomes [itex]-y/0.1= e^{-y}[/itex]. Now multiply on both sides by [itex]-0....
