So the answer is 4.4M

Simple logic we all know that 1MEGA or Million = 1000000.

Here 10^6 is define as 1000000 = 1M.

THEREFORE ---> 4.4*10^6 = 4.4M is the answer.

AS we know 10^3 ( 10 to the power of 3 ) is called Kilo and denoted as K similarly 10^6 is called Mega / Million and is denoed as M

Yes all had mentioned its true and we know that:
10^3 =10,000,
10^6 = 10,000000 .

10 to the power of 6 is represented in Mega so the answer is option D.

10^3=1000=1K;
10^6=1000000=1M;
10^-3=0.001=1m;
10^-6=0.000001=1u

4.4*10^6=4,400,000
4,400,000= 4.4million or 4.4mega= 4.4M

One mega is 10^6 = 100000.

So, 4.4 *10^6 = 4.4 M.

1 mega is 10^6 = 100000.
and, 4.4*10^6 = 4.4M.

1 kW = 1000 W = 10^3.
1 MW = 1000000 W = 10^6.
