Answer 1

Respuesta:

1.-(3x10³)(9.1x10²)=2730000

2.-(5x10⁴)(1.1x10)=550000

3.-(2.5x10²)( 3x10²)=​75000

Explicación paso a paso:

1.-(3x10³)(9.1x10²)=                

(3x1000)(9.1x100)=            

(3000)(910)=                                  

2730000=

2.-(5x10⁴)(1.1x10)=

(5x10000)(1.1x10)

(50000)(11)

550000

3.-(2.5x10²)( 3x10²)=

(2.5x100)(3x100)

(250)(300)
