Daję naj :D
a) (1/4)^5 : 1/2^8=
= [(1/2)^2]^5 : (1/2)^8 =
= (1/2)^10 : (1/2)^8 =
= (1/2)^ 2
b) 81^4/ 27^5 =
= ( 3^4)^4 : (3^3)^5 =
= 3^16 : 3^ 15 =
= 3^(16 -15)=
= 3^1 =
= 3
c) 2^10 * 3^ 10/ 6^8=
= (2*3)^10 : (6)^8 =
= 6^10 : 6^8 =
= 6^(10 -8) =
= 6^2=
= 36
a) (1/4)^5 : 1/2^8= ((¹/₂)²)⁵: (¹/₂)⁸= (¹/₂)¹⁰:(¹/₂)⁸= (¹/₂)²= ¹/₄
b) 81^4/ 27^5= (3⁴)⁴/ (3³)⁵= 3¹⁶/3¹⁵=3¹=3
c) 2^10 * 3^ 10/ 6^8= (2*3)¹⁰/6⁸=6¹⁰/6⁸=6²=36
a) (1/4)⁵ : 1/2⁸ =
= 1/1024 : 1/256 =
= 1/1024 : 256 =
= 1/4
=============================
b) 81⁴ / 27⁵ =
= 43046721 / 14348907 == 3
c) 2¹⁰ * 3¹⁰/ 6⁸ =
= (2 * 3)¹⁰ : (6)⁸ =
