    4096/100+ √4096/10000 + √4096/1000000 + √4096/100000000
    =√4096 / 10 + √4096/ 100 + √4096/ 1000 + √4096/ 10000
    =64/10 + 64/100 + 64/1000 + 64/10000
    =6.4 + .64 + .064 + .0064

    Correct Option: C

    4096/100+ √4096/10000 + √4096/1000000 + √4096/100000000
    =√4096 / 10 + √4096/ 100 + √4096/ 1000 + √4096/ 10000
    =64/10 + 64/100 + 64/1000 + 64/10000
    =6.4 + .64 + .064 + .0064
    = 7.1104

  1. If √5 = 2.24, then the value of 3√5 / 2√5 - 0.48 is ?
    1. 0.168
    2. 1.68
    3. 16.8
    4. 168

  1. View Hint View Answer Discuss in Forum

    Given expression = 3√5 / 2√5 - 0.48
    = (3 x 2.24) / (2 x 2.24) - 0.48
    = 6.72 / 4.48 - 0.48
    = 6.72 / 4

    Correct Option: B

    Given expression = 3√5 / 2√5 - 0.48
    = (3 x 2.24) / (2 x 2.24) - 0.48
    = 6.72 / 4.48 - 0.48
    = 6.72 / 4
    = 1.68

    122.76 / 15.50 = 12276/1550
    = (12276 / 155) x (1/10)

    Correct Option: B

    122.76 / 15.50 = 12276/1550
    = (12276 / 155) x (1/10)
    = 79.2 / 10
    = 7.92

    Given expression = [ (.538)2 - (.462)2 ] / .076
    = [(.538 + .462)(.538 - .462)] /.076
    =.076 / .076

    Correct Option: C

    Given expression = [ (.538)2 - (.462)2 ] / .076
    = [(.538 + .462)(.538 - .462)] /.076
    =.076 / .076
    = 1
