Problem Statement

(i) Solve the simultaneous inequalities, x<14xx<\frac{1}{4x} and x<0x<0; i.e. find a single inequality equivalent to the two simultaneous inequalities. (ii) What is the greatest integer that satisfies both inequalities 4x+13<04x+13 < 0 and x2+3x>16x^{2}+3x > 16. (iii) Give a rational number between 11/2411/24 and 6/136/13. (iv) Express 100000 as a product of two integers neither of which is an integral multiple of 10. (v) Without the use of logarithm tables evaluate 1log236+1log336.\frac{1}{\log_{2}36}+\frac{1}{\log_{3}36}.
