25. Tyd vir selfassessering

26. KOPKRAPPERS!

a) Wat sal die antwoord van die volgende wees? Probeer dit kry sonder ellelange bewerkings!

o = 1 1 2 × 1 1 3 × 1 1 4 × 1 1 5 × 1 1 6 × 1 1 7 × 1 1 8 size 12{o= left (1 - { { size 8{1} } over { size 8{2} } } right ) times left (1 - { { size 8{1} } over { size 8{3} } } right ) times left (1 - { { size 8{1} } over { size 8{4} } } right ) times left (1 - { { size 8{1} } over { size 8{5} } } right ) times left (1 - { { size 8{1} } over { size 8{6} } } right ) times left (1 - { { size 8{1} } over { size 8{7} } } right ) times left (1 - { { size 8{1} } over { size 8{8} } } right )} {}

b) As jy so sou aanhou met die patroon tot by . . . 1 1 25 size 12{ times left (1 - { { size 8{1} } over { size 8{"25"} } } right )} {} , wat sal die antwoord dan wees?
