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.

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.

To get 10-3/1000 = 10-6.

Multiplication and division with 1000.

= 4.38 x 10"3.

= 4.38 x 10-3 x (1000/1000).

= (4.380 x 1000) x (10-3/1000).

= 4380 x 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.

This expression is mention in 10^-6. So,

4.38*10^-3 = 0.00438.

4380*10^-6 = 0.00438.

Equal . Option A.

It is given 4.38*10^-3 to express in 10^-6
Divide both side by 1000
4.38/10^3*10^-3/10^3 = 438*10^-6

They are asking the value that should be in 10^-6 just shift 0.380 to left and decrease the power.

4.38*10^-3=4.38*10^-3*(10^3/10^3)
=4380*10^-3*10^-3
=4380*10^-6

By increasing point denomination, minus raise to value also increase.

Muneem Gour said:   10 years ago
Now 4.38*10^-3.

4.38*10^-3*10^-6*10^6.

So and is 4380*10^-6.
