In mathematical problem, the numbers are multiplied & powers are added.
Therefore, 6*5=30 & 10^3+5=8 so, 30*10^8.
Therefore, 6*5=30 & 10^3+5=8 so, 30*10^8.

6*10^3=6000 and 5*10^5=500000
When you multiply the answers you have 3000000000, there4 this can be written as
3*10^9 or 30*10^8

(6*5)*(10^(5+3))=30*10^8
In mathematical problem, the numbers are multiplied, power are added and finally multiply both.

Because of both digits (6 and 5) are multiply directly with each other while the powers of multiplier will be additive.

It's very easy anser.in multiply 6*5. If both bases r equal then powers must be added
So (6*5)*(10^3+10^5)=30*10^8
So (6*5)*(10^3+10^5)=30*10^8

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

(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

Powers are added during multiplication so 6*5=30.
10^3+5=10^8 therefore 30*10^8.
10^3+5=10^8 therefore 30*10^8.

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