Answer 1

Answer:

2) 3+1root5/4

3)rationalising we get 49/46 + 9/46(root3)

a=49/46  b= -9/46

4)i) 1.2727..

x=1.27 bar

multiply by 100

100x=127.27272 or 100x-x = 127.27272

x=99/126 = p/q

ii) x=0.23535

multiply by 100

subtract , 99x=23.3

x=23.3/99 or x=233/990 = p/q

5) i) 4x9 - 8x6 +15x2 + 15 = 33

ii)  4x6^2 + 1x4^3 + 2x3^1 = 214
