0.000032 * 1000,000 = 32.

3.2*10^10^-5.

(32/10)*10^-5.

32*10^(-5-1).

32*10^-6/

32 uA.

3.2/100000= 0.000032.
Now we know 1µ = 10^6.

So,
0.000032*10^6= 32 µA.

Lets us discuss simply manner.

First we should know that 1µA = 10^-6A-----(1).

THEN, 3.2*10^-5 {now move the left side to decimal point then inc +0 on right} 32*10^-6.

32*10^-6 = 32*1µA (because from eq(1) we studied that 1µA = 10^-6).
= 32µA is the answer

3.2 x 10^-5 = 0.032 x 10^-3.
= 0.000032.

Then converting it in metric prefix.
Shift dec point 6 digit right.
= 32 x 10^-6.
= 32uA.

3.2*10^-5
We can write 3.2 as 32/10.

32/10*10^-5.

32*10^-5-1.

32*10-6.

So we know,
10^-6= 1 micro.

32*1 micro.

32u answer.
