  1. Mocnina kladného a záporného čísla

  2. ( - 8 )2 =( - 2 )5 =( - 0,2 )4 =( - 1 )6 =( - 5 )3 =- 3 4 =( - )3 = Počítej zpaměti, výsledky piš pod sebe :

  3. Kontrola:( - 8 )2 = 64( - 2 )5 = - 32( - 0,2 )4 = 0,0016( - 1 )6 = 1( - 5 )3 = - 125 - 3 4 = - 81( - )3 = - -

  4. Počítej do sešitu:a)(-7 + 4 )4=b) ( - 7 – 3 )3=c) - ( - 2 + 4 – 9 )5=d) ( - 4 )4-( - 4 )5 =

  5. Kontrola:a)(-7 + 4 )4 = 81b) ( - 7 – 3 )3 = - 1000c) - ( - 2 + 7 – 8 )5 = 243d) ( - 4 )4 -( - 4 )5 = 1280

  6. Počítej dál:e) [( 1 + 1 )3+1]4 =f) ( 5 - 7 - 8 + 3 )3 =g) ( - 3 )4 -( - 3 )5 = h) - 4 4 + ( - 4 )5 = i) - 4 4 + 4 5 =

  7. Kontrola:e) [( 1 + 1 )3 +1]4 = 94 = 6561f) ( 5 - 7 - 8 + 3 )3 = ( - 7 )3 = 343 g) ( - 3 )4 -( - 3 )5 = 81 + 243 = 324h) - 4 4 + (- 4 )5 = - 256 - 1024 = -1280i) - 4 4 + 4 5 = -256 + 1024 = 768

  8. Počítej: ( - 5 + 2)5 = ( - 5 - 2)5 = - ( - 5 + 2)5 = ( 5 - 2)5 = 55 - 25 =

  9. Kontrola: • ( - 5 + 2)5 = (-3)5 = - 243 • ( - 5 - 2)5 = (-7)5 = - 16 807 • - ( - 5 + 2)5 = - (-3)5 = + 243 • ( 5 - 2)5 = ( 3 )5 = 243 • 55 - 25 = 3125 – 32 = 3093

  10. Doplň mocninu čísla 10: 3 250 000 = 3,25 . _____ 1 200 000 000 = 1,2 . _____ 72 150 = 7,215 . _____ 86 300 000 = 8,63 . _____ 1 870 000 000 = 1,87 . _____

  11. Kontrola: 3 250 000 = 3,25 . 106 1 200 000 000 = 1,2 . 109 72 150 = 7,215 . 104 86 300 000 = 8,63 . 107 1 870 000 000 = 1,87 . 109
