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 :)  

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 [latex] frac{a^4}{16b^4} [/latex]   5. [latex] a) 2^7 * 5^7 = (2 * 5)^7= 10^7 = 10 000 000 b) (frac{1}{2})^5 * 4^5 =(frac{1}{2} * 4)^5 = 2^5 = 32 c) 16^10 : 8^10 = (16 : 8)^10 = 2^10 = 1024 d) (3/5)^4 :(frac{1}{5})^4 = (frac{3}{8} x frac{8}{1})^4 = 3^4 = 24 e) 0,2^3 * 10^3 = (0,2 x 10)^3 = 2^3 = 8 f) (-frac{1}{3})^3 :(frac{1}{9})^3 = (-frac{1}{3} * frac{9}{1})^3 = (-3)^3 = -27 g) (-0,2)^9 : 0,1^9 = ( - 0,2 : 0,1)^9 = (-2)^9 = - 512 h) (frac{4}{3})^3 * (frac{3}{4})^3 = (frac{4}{3} * frac{3}{4})^3 = 1^3 = 1 [/latex]
