Answer:

Scientific notation of the multiplication is
2.42* 10^(25)

Explanation:

(2.2* 10^(7))(5* 10^(8))(2.5* 10^(3))(8.8* 10^(5) )

=
(2.2* 5* 2.5* 8.8)10^((7+8+3+5))

[Since
10^(a)* 10^(b)=10^((a+b)) ]

=
242* 10^(23)

=
2.42* 10^(25)

Therefore, the scientific notation of the multiplication is
2.42* 10^(25)
