a) √16•√9 = 4•3 = 12
b) √100•√64 = 10•8 = 80
c) √6²•√5² = 6•5 = 30
d) √2•√9•√3 = 2•9•3 = 54
e) √16•√25•√49 = 4•5•7 = 140
f) √11²•√2²•√3⁴ = 11•2•3² = 22•9 = 198
g) ³√27•³√64 = 3•4 = 12
h) ³√8•³√64 = 2•4 = 8
i) ³√7³•³√9³ = 7•9 = 63
j) ³√27•³√64•³√125 = 3•4•5 = 60
(nie mam pewności w tych dwóch)
k) ³√3⁶•³√5³•³√2⁹ = 3³•5•2⁶ = 27•5•64 = 8640
l) ³√4⁹•³√6³•³√27 = 4⁶•6•3 = 4096•6•3 = 73,728
