Question

comparati nr. x si y ; x=(5^3:5)^6 ; y=(25×5)^3 ; b) x=2^155 ; y=3^93

Answer 1

a) 5^3:5=5^2=>(5^2)^6=5^12, y=25=5^2=> (5^2*5)^3=(5^3)^3=5^9 => y<x
b) putem face o aproximare, in loc de 2^155 incercam 2^15, iar in loc de 3^93 incercam 3^9. 2^15~=32.000, iar 3^9~=19.000. deci 2^155>3^93. Poti incerca si alte exemple eventual
