Answer 1

Answer:

The value of the given expression is  450000000000

Step-by-step explanation:

Given expression as :

$(5\times 10^{3})\times (9\times 10^{7})$

Or, ( 5 × 9 ) × $( 10^{3})\times ( 10^{7})$

or, 45  × $( 10^{3})\times ( 10^{7})$

Or, since base is same , then power is added

So, 45  × $( 10^{10})$

∴  450000000000

Hence The value of the given expression is  450000000000   Answer
