Question

(4^31+6•32^12-5•16^15):(8^21-5•8^20)-1=

Answer 1

Răspuns:  2/3

(4³¹+ 6 x 32¹²- 5 x 16¹⁵) : (8²¹ - 5 x 8²⁰) - 1 = [(2²)³¹ + 2 x 3 x (2⁵)¹² - 5 x (2⁴)¹⁵] : [(2³)²¹ - 5 x (2³)²⁰] - 1 =

(2⁶² + 3 x 2⁶¹ - 5 x 2⁶⁰) : (2⁶³ - 5 x 2⁶⁰) -1 =      

[2⁶⁰ x (2² + 3 x 2 - 5)] : [2⁶⁰ x (2³ - 5)] - 1 =

[2⁶⁰ x (4 + 6 - 5)] : [2⁶⁰x (8 - 5)] - 1 =

[2⁶⁰ x 5] : [2⁶⁰x 3] - 1 =

5/3  -  1 =
