Answer 1

Answer:

(i) 1.080

(ii) 0.655

Step-by-step explanation:

(i) (√2+1)/√5

= (√2+1)/√5 * (√5/√5)

= √5(√2+1)/(√5*√5)

= (√10+√5)/5

= (3.162+2.236)*2/10

= (5.398)2/10

= 10.796/10

= 1.0796

= 1.080

(i) (√10-√5)/√2

= (√10-√5)/√2 * (√2/√2)

= √2 (√10-√5)/(√2*√2)

= (√20-√10)/2

= (√4*√5 - √10)/2

= (2√5 - √10)/2

= (2(2.236) - (3.162))/2

= (4.472-3.162)/2

= 1.31/2

= 0.655
