Question

(5 x 10^3) × (9 × 10^7)​

Answer 1

The value of the given expression is 450000000000

Explanation:

Given expression as :

`(5* 10^(3))* (9* 10^(7))`

Or, ( 5 × 9 ) ×
`( 10^(3))* ( 10^(7))`

or, 45 ×
`( 10^(3))* ( 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
