Question

Oblicz
a) (√3- √12+√27) x √3
b) √45 x √5 - ∛2 x ∛4
c) √1 3/4 : √3 15/16 + ∛5 + ∛25
d) [2 do potęgi 2 - √1 9/16 : (-1 1/4) do potęgi 2 x (-2 1/2) do potęgi 3

Answer 1

A)=(√3-2√3+3√3)*√3=2√3*√3=6
b)= 3√5*√5-∛8=15-2=13
c)=√7/2*4/√63+∛5+∛25=√7/2*4/3√7+∛5+∛25=2/3+∛5+∛25
d)=[4-5/4:25/16*(-125/8)=4-5/4*15/25*(-125/8)=4+375/32=4+11 23/32=15 i 23/32
