Pls help me with this question

Answer 1

Answer:

a=59 and b=34

Step-by-step explanation:

(a) (5 + 2√3)/(7-4√3)

= (5 + 2√3)(7+4√3)/(7-4√3)(7+4√3)

= (5 + 2√3)(7+4√3)/49-48 = (5 + 2√3)(7+4√3)

= 35+20√3+14√3+24

= 59 + 34√3 = a +b√3

therefore a=59 and b=34

(b) similarly as done above first rationalise the dinominator and then solve
