1kw = 1000w
1mw = 10^-3 = 0.001w.
So 135w = 0.135mw.
mw/kw = 0.135/1000 = 0.000135(1.35 * 10^-4).

135 milliwatts = 13.5 watts.
now 1 kilowatt = 1000 watts.
so, 1 watt = 0.001 kilowatts.

Hence 135 milliwatts = 13.5 * 0.001 kilowatts,
=> 13.5 * 10^-3 kW,
=> 1.35 * 10^ -4,
=> Ans= A.

1000watts=1kw.
1milliwatts=?
So,1 milliwatts=10^-6kw.
So 135mw=135x10^-6KW=1.35X10^-4KW.

1kw=10^3w,
1kw=10^6mw,
So,135mw = 135x10^-6 = 1.35x10^-4kw.

135 milliwatts = 135 x 10^-3 watt = 135 x 10^-6.

135 x 10^-6 = 13.5 x 10^-5 = 1.35 x 10^-4 is the answer.

135 milliwatt =135 * 10^-3 watts.
Numerically, 1 watt = 1/1000 KW,
Therefore, (135 * 10^-3) watts = (135 * 10^-3)/1000,
= 135 * 10^-6 or 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).

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.

1000 mw = 1 w.
135 mw = 0.135 w.

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