2.3¹¹:3⁸/3²=3³:3²=3 B
3. (1¾)² D
4. V9+16= V9+V16=3+4= 7 D
5.V1 i 16/9=V25/9=5/3 A
6. 8300 km²= 8300 × 1000000= 8300000000m²=8,3×10⁹
7.V54=V9×6=3V6
V24= V4×6=2V6
3V6+2V6/V6=5V6/V6 (pierwiastki skracamy)=5
8. (6X²Y³)²:(36X⁶Y³)= (36X⁴Y⁶):(36X⁶Y³)=X‐²Y³
(V2)-²×3³=(1/V2)²×3³=½×27=27/2=13½
9. 2⁷×(4⁵:2³)²/8³=2⁷×[(2²)⁵:2³)²/8³=2⁷×(2¹⁰:2³)²/(2³)³=2⁷×2¹⁴/2⁹ =2²¹/2⁹= 2¹²
2¹²×¼=2¹²/2²=2¹⁰
10.³V7³×2+7²×7+5×7³=³V7³×2+7³+5×7³=³V7³×(2+1+5)=³V7³×8=³V7³×2³=³V14³= 14
Na 11. nie mam pomysłu
