Question

0. Calcule:
2.10⁵+ 3.10⁵
9.10-³- 7.10-³
1.25.10⁷ + 3.4.10⁷
2.3.109³ x 1.15.10²
6.10-² + 1.2.10³​

Answer 1

Resposta: *2.10⁵+3.10⁵* =2.(10.10.10.10.10)+3.(10.10.10.10.10)=2.100,000+3.100,000=200,000+300,000=500,000

*9.10³-7.10³* =9.1000-7000=2000

1.25.10⁷+3.4.10⁷=1.25.10,000,000+3.4.10,000,000=250,000,000+120,000,000=370,000,000

6.10²+1.2.10³=6.100+1.2.1000=600+2000=2600
