Potrzebuje na teraz proszę ;) Z góry dziękuje zadanie w załączniku zadanie 1 oraz 5 :]
1.
a) (3x)³ = 27x³
b) (-2a)⁵ = -32a⁵
c) (-xy)⁸ = x⁸y⁸
d) (-ab²)³ = -a³b⁶
e) (-3xy²)₄ = 81x⁴y⁸
f) (-x²y³)⁵ = -x¹⁰y¹⁵
g) ⁴ = a⁴/16
h) ³ = -x³/8
i) ⁴= a⁴/16b⁴
5.
a)2^7 x 5^7 = (2 x 5)^7= 10^7 = 10 000 000
b)(1/2)^5 x 4^5 =(1/2 x 4)^5 = 2^5 = 32
c) 16^10 : 8^10 = (16 : 8)^10 = 2^10 = 1024
d) (3/5)^4 :(1/5)^4 = (3/8 x 8/1)^4 = 3^4 = 24
e) 0,2^3 x 10^3 = (0,2 x 10)^3 = 2^3 = 8
f) (-1/3)^3 :(1/9)^3 = (-1/3 x 9/1)^3 = (-3)^3 = -27
g) (-0,2)^9 : 0,1^9 = ( - 0,2 : 0,1)^9 = (-2)^9 = - 512
h) (4/3)^3 x (3/4)^3 = (4/3 x 3/4)^3 = 1^3 = 1
przy czym x = razy, a ^ = do potęgi
Mam nadzieję, że pomogłam :)
