= 2⁴⁰(1+2)/3²⁵
= 2⁴⁰ₓ3/3²⁵
= 2⁴⁰/3²⁴
= (2¹⁰)⁴/(3⁶)⁴
= 1024⁴/729⁴ supra
= 19⁷/(2⁴)⁷
= 19⁷/16⁷ supra
Ti-am facut cateva exemple, in rest incearca sa te descurci dupa model ..
Ok sister ?
hai ca ti-am mai facut unul
- (4ₓ5⁴⁰ + 2ₓ5⁴¹ + 2ₓ5⁴²)/2¹⁰⁶ =
= (2²ₓ5⁴⁰ + 2ₓ5⁴¹ + 2ₓ5⁴²)/2¹⁰⁶
= 2ₓ5⁴⁰(2 + 5 + 2ˣ5²)/2¹⁰⁶
= 2ˣ5⁴⁰ˣ57/2¹⁰⁶
= 2ₓ57ₓ5⁴⁰/2ₓ2⁶ₓ2¹⁰⁰
= 2ₓ57ₓ(5²)²⁰/2ₓ64ₓ(2⁵)²⁰
= 2ₓ57ₓ25²⁰/2ₓ64ₓ32²⁰
57 < 64
25 < 32
fractia este sub ... unitara :)))
- (3²⁴ + 3²³ - 2ₓ3²²)/(9¹¹ + 9¹²) =
= 3²²(4 + 2 - 2ₓ1)/9¹¹(1 + 10)
= 3²²ₓ4/9¹¹ₓ10
= 3²²ₓ4/(3²)¹¹ₓ10
= 3²²ₓ4/3²²ₓ10
4 < 10 subunitara
