Respuesta :

That would be A.

2.5*2*10^(10-7)=5*10^3

Answer: The correct option is,

A. [tex]5.0\times 10^3[/tex]

Explanation:

Given expression,

[tex](2.5\times 10^{10})\times (2.0\times 10^{-7})[/tex]

[tex]=2.5\times 2.0\times 10^{10-7}[/tex]

( By using product property of exponent i.e. [tex]a^m\times a^n = a^{m+n}[/tex] )

[tex]=5.0\times 10^3[/tex]

Therefore,

OPTION A is correct.
