Question

Doprowadż do najprostszej postaci :

( a3 * a^ )5 = ?

[( a4 * a^ ) 5 : ( a6 * a4 ) ^ ] : ( a9 : a8 ) 6 = ?

53 * 52 * 57 : ( 512 * 54 ) 2 : 520 = ?

3 – ( 5,5 -4 ) ^ + ( 32 – 12 ) 2 = ?

[ 3 * a5 * a^ – 5 * a7 ] : ( -2 * a4 * a3 ) =?

( 515 + 513 ) * 1024 : ( 514 + 512 ) * 4 5 = ?

Pomóżcieee ! ;D < 33 Dajee NAj !!!!!!!

Answer 1

a)(a³·a)⁵=a¹⁵·a⁵=a¹⁰

b)[(a⁴·a)⁵:(a⁶·a⁴)]:(a⁹:a⁸)=[(a²⁰·a⁵):a¹⁰:(a⁵⁴:a⁴⁸)=a²⁵:a¹⁰:a¹⁰²=a⁻⁸⁷

c)53··52·57:(512·54)²:512=157092:764411904:512=0,000000040138

d)3-(5,5-4)²+(32-12)²=3-1,5²+20²=3-2,25+400=400,75

e)[ 3 · a5· a⁻⁵ · a⁷ ] : ( -2 · a⁴· a³ ) =[3a⁷]:(-2a⁷)=-1,5a°

f)( 515 + 513 )· 1024 : ( 514 + 512 )· 4 5 =(264195·1024):(1026·45)=270535680:46170
