2 bình luận về “a, 5m² 12dm²=………………m² b, 30006cm² = ……………..m² c, 4,2m²=…………….cm² d, 9m² 34cm² = ………….”

1. Giải đáp+Lời giải và giải thích chi tiết:

   a, 5m² 12dm²=5,12 m²

   b, 30006cm² = 3,0006 m²

   c, 4,2m²=42000 cm²

   d, 9m² 34cm² = 9,0034  cm² 

   _______________________________________________________

   1 m² = 100 dm² = 10000cm²

   1 dm² = ${\displaystyle \frac{1}{100}}$ m²

   1 cm² = ${\displaystyle \frac{1}{10000}}$ m²

   Trả lời
2. a) $5m^{2}12d{m}^2=5m^2+{\displaystyle \frac{12}{100}}{m}^2=5m^2+0,12m^2=5,12m^2$

   b) $30006c{m}^2={\displaystyle \frac{30006}{10000}}{m}^2=3,0006m^2$

   c) $4,2m^2=4,2c{m}^2.10000=42000c{m}^2$

   d) $9m^{2}34c{m}^2=9c{m}^2.10000+34c{m}^2=90000c{m}^2+34c{m}^2=90034c{m}^2$
