zad.1 oblicz, korzystająć z własności potęg:
a)
b)
c)
zad.2
Jakim procentem liczby a jest liczba b:
1)
a) (2³)² * 2⁴ 2⁶⁺⁴
= -------------= ------- = 2¹⁰ ⁻ ⁵ = 2⁵ = 32
2¹¹ : 2⁶ 2¹¹⁻⁶
3¹² * 3 ⁻¹⁰ 3¹²⁻¹⁰
= ----------------- = ------------=3²⁻⁴ = 3⁻² = 1/9
3⁴ 3⁴
a⁻¹⁵ : a⁻³ *a⁻² a⁻¹⁵ ⁺³ ⁻²
= --------------------= ------------ = a⁻¹⁴ ⁺²³=a⁹
a⁻⁸ : a¹⁵ a⁻⁸⁻¹⁵
jezeli pojawiły się kwadraciki, to tam jest -
2)
a = 1 * 2 + 3 = 2+3 = 5
b = (3/-1) * (- 4/3) = -3 * (-4/3) = 4
teraz:
4/5 * 100% = 400/5% = 80%
