Question

Comparați Nr. a) x=2⁹⁶+2⁹⁸+2¹⁰⁰ si y=2¹⁰¹+2⁹⁹+2⁹⁷
b) x=3⁵⁷-3⁵⁵-3⁵³ si y=5⁴³-125¹⁴
Va rog urgent dau coroana!!!!​

Answer 1

Răspuns:

a)

x=2^96•(1+4+16)=2^96 • 21

y=2^97•(16+4+1)=2^97 • 21 =>y > x

b)

x=3^53•(81-9-1)=3^53 • 71

y=5^43 - (5^3)^14=5^43 - 5^42=5^42•(5-1)=5^42 • 2^2 => x > y
