3. Oblicz a) V125 + V b) V125 - V64 d) V512 - V-216 112-2231 h) 46-09-12 c) V-1000 + V27 ) (37 +(277 & 1897 - V na teraz​

Answer 1

a. ∛125 + ∛8 = 5 + 2 = 7

b. ∛125 - ∛64 = 25 - 4 = 21

c. ∛-1000 + ∛27 = -10 + 3 = -7

d. ∛512 +  ∛-216 = 8 + 6 = 14

e. (√3)² + (√7)² = 3 + 7 = 10

f. √11² - 2√3² = 11 - 2·3 = 11-6 = 5

g. (∛9)³ - ∛7³ = 9 - 7 = 2

h. 4∛6³ - (∛-12)³ = 4 · 6 - (-12) = 24 + 12 = 36
