Question

Proszę o pomoc w zadaniu z matematyki klasa II gimnazjum... 11. Oblicz : a ) 4⁵ * 6⁵ ----------- = 24⁵ b ) ( 16⁴ : 8⁴ ) * 5⁴ -------------------- = 2⁴ c ) ( 20⁵ * 5⁵ ) : ( 80⁵ : 16⁵ ) ---------------------------------- ( 60⁵ : 15⁵ ) d ) (( -5 )⁸ * 3⁸ ) ³ * (( -30)⁶ : ( -5 )⁶)⁴ -------------------------------------------- = (3²*5²*6²) ¹²

Answer 1

11. a)  4⁵ * 6⁵ - .... = 24⁵ 
(4 * 6)⁵ - .... = 24⁵ ( to wychodzi 7962624 )
24⁵-0=24⁵ 
b) (16⁴ : 8⁴)*5⁴....=2⁴ 
(16 : 8 )⁴ * 5⁴ .... = 2⁴
2⁴ * 5⁴ .... =  2⁴
(2 * 5)⁴ ... = 2⁴
10⁴ : 5 = 2⁴
c)  ( 20⁵ * 5⁵) : (80⁵ : 16⁵) = (20 * 5)⁵ : (80 : 16)⁵ = 100⁵ : 5⁵ = (100 : 5)⁵ =20⁵ 
(60⁵ : 15 ⁵) = (60 : 15)⁵ = 4⁵
d) nie wiem
