Question

Oblicz wartość wyrażenia:
(25³ : 2 ⁴ x 4-½)²
----------------------- =
(25⁻³ x 2 ⁴ x 5⁻½)⁻²

Answer 1

25³ : 2 ⁴ x 4-½)²
----------------------- =
(25⁻³ x 2 ⁴ x 5⁻½)⁻²

= (25do szóstej * 1/2 do ósmej * 2 do - drugiej) : (25 do szóstej* 2 do - ósmej *5 )= (5 do dwunastej * 1/2 do ósmej * 1/2 do drugiej) : ( 5 do trzynastej * 1/2 do ósmej) = 5 do - pierwszej * 1/2 do kwadratu = 1/5 * 1/4 = 1/20

Answer 2

(25³:2⁴*4-½)²/(25⁻³*2⁴*5-½)⁻²=25⁶:2⁸*4²-(½)²/25⁶*2⁻⁸*5²-(½)⁻²=16/25
