Oblicz:
1.(3¹⁸+3¹⁶)×27/ (3¹⁴+3¹²)×9=
2. (1+0,5)² - (1-0,5)³=



Odpowiedź :

1.(3¹⁸+3¹⁶)×27/ (3¹⁴+3¹²)×9=3¹⁶(3²+1)x3³/3¹²(3²+1)x3²=
3¹⁹/3¹⁴=3⁵
2. (1+0,5)² - (1-0,5)³= (1,5)²-(0,5)³=2,25-0,125= 2,125
1.(3¹⁸+3¹⁶)×27/ (3¹⁴+3¹²)×9=3¹⁶(1+3²)*3³/3¹²(1+3²)3²=(3¹⁹/3¹⁴)*(10/10)=3⁵=243
2. (1+0,5)² - (1-0,5)³= (1,5)² - (0,5)³= 2,25 - 0,625=1,625
