Question

Calculați x^y+y^x pentru: x=8³³÷[4³²×2³⁴+(2⁵×2²⁰)⁵÷(16×2²³)+(7⁵÷7⁵-1)³²×4]. Pls acum dau coroană!!!​

Answer 1

x = (2^3)^33 : [ (2^2)^32 * 2^34 + (2^25)^5 : (2^4 * 2^23) + (7 + 1)^32 * 4]

x = 2^99 : [ 2^64 * 2^34 + 2^125 : 2^27 + 8^32 *2^2]

x = 2^99 : ( 2^98 + 2^98 + (2^3)^32 * 2^2)

x = 2^99 : (2^98 + 2^98 + 2^96 * 2^2)

x = 2^99 : (2^98 + 2^98 + 2^98)

Dam factor comun pe 2^98:

x = 2^99 : [2^98(1 + 1 +1)]

x = 2^99 : (2^98 * 3)

x = (2^99 : 2^98) * 3

x = 2 * 3

x = 6
