Answer:
The value of the given expression is 450000000000
Step-by-step explanation:
Given expression as :
[tex](5\times 10^{3})\times (9\times 10^{7})[/tex]
Or, ( 5 × 9 ) × [tex]( 10^{3})\times ( 10^{7})[/tex]
or, 45 × [tex]( 10^{3})\times ( 10^{7})[/tex]
Or, since base is same , then power is added
So, 45 × [tex]( 10^{10})[/tex]
∴ 450000000000
Hence The value of the given expression is 450000000000 Answer
