It's simple given equation is 4.38 * 10^-3.
Now remember 10^-3/1000 = 10^-6.
Now divide and multiply this value with 1000.
So it will 4.38 * 1000 * 10^-3/1000.
It will become 4.38 * 1000 * 10^-6 (as we know 10^-3/1000 = 10^-6).
4.38 * 1000 = 4380 so answer will come to 4380 * 10^-6.
Now remember 10^-3/1000 = 10^-6.
Now divide and multiply this value with 1000.
So it will 4.38 * 1000 * 10^-3/1000.
It will become 4.38 * 1000 * 10^-6 (as we know 10^-3/1000 = 10^-6).
4.38 * 1000 = 4380 so answer will come to 4380 * 10^-6.

We know that;
10^-3 is milli,
10^-6 is micro,
Here;
1 milli=1000micro.
4.38 milli=4.38 *1000micro.
=4380micro,
= 4380 * 10^-6.
10^-3 is milli,
10^-6 is micro,
Here;
1 milli=1000micro.
4.38 milli=4.38 *1000micro.
=4380micro,
= 4380 * 10^-6.

=4.38 x 10^-3÷10^-6
As we know 10^-6=1÷10^6
=4.38 x 10^-3÷(1÷10^6)
=4.38 x 10^-3 x 10^6
=4.38 x 10^3
=4380.00
=4380 micro A
=4380 x 10^-6 A.
As we know 10^-6=1÷10^6
=4.38 x 10^-3÷(1÷10^6)
=4.38 x 10^-3 x 10^6
=4.38 x 10^3
=4380.00
=4380 micro A
=4380 x 10^-6 A.

10^3 ÷ 10^-6
10^3 is came,
4.38÷1000 = 4380.
10^3 is came,
4.38÷1000 = 4380.
