2.Theseirrationalnumbersliebetweenwhichtwointegers?
< 𝜋 < < 30 < < 50 < < 129 <
3.Useyourcalculatortoevaluatetheseirrationalnumbers,roundedtotwodecimalplaces:
27 = (2 d.p. ) 10! = (2 d. p. ) 𝜋! + 5 = (2 d.p. )
4.Simplifyfully(leaveasasquarerootofasmallervalue,multipliedbyaninteger):
27 = 48 =
75 = 1000 =
5.Expandandsimplifyfully:
(2𝑥 + 3)(𝑥 − 1)
