Given:
(6x10^3).
(5x10^5).
{(10^3)*(10^5)} = 10^3+5 = 10^8 => [(a^n)*(a^m)=a^n+m].
6*5=30.
Therefore Answer is 30*10^8.
So answer is Option B.
(6x10^3).

Therefore Answer is 30*10^8.
So answer is Option B.

6*5=30.
According to mathematical rule we have to add the powers so the powers 5+3=8 so the answer is 30x10^8.

Simple. In multiplication base increses.

Add the power and then multiply the base term.

This is very small problem you have known the powers addition.
That is.
You first multiply the both 6&5 then added the powers.
Therefore.
(6*10^3) (5*10^5) = (6*5) (10^3+5) =30*10^8.
Then you get the answer.

(6x10^3)(5x10^5)
(6x5x10^3+5)
(30x10^8)
So ans is Option B
(6x5x10^3+5)
(30x10^8)
So ans is Option B

When we are multiplying of these numbers the powers of those numbers are added.

(6 x 10^3)=6000
(5 x 10^5)=500000
6000 x 500000 = 3000000000
3000000000 = 30x10^8
(5 x 10^5)=500000
6000 x 500000 = 3000000000
3000000000 = 30x10^8

Its very easy that-6*5=30;
In exponent 10^(5+3)=10^8
So the ans is 30*10^8
In exponent 10^(5+3)=10^8
So the ans is 30*10^8
