1000 mw = 1 w.
135 mw = 0.135 w.
So 1000 w = 1 kw.
0.135 w = 1.35*10-4.
135 mw = 0.135 w.
So 1000 w = 1 kw.
0.135 w = 1.35*10-4.

Consider that we have 1 milliwatt.
Now,
=> 1 milliW = 1*10^-6 KW.
=> 135 milliW = x KW.
=> (cross multiplying above).
x = 135*10^-6 KW.
x = 1.35*10^-4 KW (shifting upto 2 decimal points).
Now,
=> 1 milliW = 1*10^-6 KW.
=> 135 milliW = x KW.
=> (cross multiplying above).
x = 135*10^-6 KW.
x = 1.35*10^-4 KW (shifting upto 2 decimal points).

Given: 135milliwatt.
=> 135x10^-3 : To convert it into kilowatts, lets multiply and divide it by 10^3.
=> 135x10^-3 x 1/10^3 KW.
=> 135x10^-6 KW (cause when denominator goes to numerator, '+' becomes "-" so).
=> 135x10^-6 KW => 13.5x10^-5 KW => 1.35x10^-4 KW.
Hence the answer is 1.35x10^-4 KW.

First understand the logic principles ------>
0 --------> Milliwatts.
10 --------> Watts.
1000 -------> K.watts.
Conversions ------------------------->
135 milliwatts = 13.5 watts (135/10=13.5).
Now 1 K.W = 1000 watts.
1. watts = 0.001 kW.
135 m.W = 13.5 Watts = 13.5*0.001 kW.
= 1.35*0.00001kW.
= 1.35*10^-4.
0 --------> Milliwatts.
10 --------> Watts.
1000 -------> K.watts.
Conversions ------------------------->
135 milliwatts = 13.5 watts (135/10=13.5).
Now 1 K.W = 1000 watts.
1. watts = 0.001 kW.
135 m.W = 13.5 Watts = 13.5*0.001 kW.
= 1.35*0.00001kW.
= 1.35*10^-4.

1mW = 0.001W.
1W = 0.001KW.
Therefore, 1mW = .000001 kW.
Hence 135mW = 135*.000001 kW.
=1.35*10^-4 kW answer.
1W = 0.001KW.
Therefore, 1mW = .000001 kW.
Hence 135mW = 135*.000001 kW.
=1.35*10^-4 kW answer.

135*10^-3w.
To convert to KW.
Divide and multiply by 10^3 to reduce the unit to W.
Again to reduce the unit to KW divide by 10^3.

1.35 *10^-4 kW.
1.35 *10^-4 *10^3W.
1.35 *10^-1W.
So 135 mW.
1.35 *10^-4 *10^3W.
1.35 *10^-1W.
So 135 mW.

We know,
135mW = 135/1000w = .135w = . 35/1000 kw.
Which is equal to option (A).
135mW = 135/1000w = .135w = . 35/1000 kw.
Which is equal to option (A).
