Answer:
123
Step-by-step explanation:
To do this you have to move the decimal place 4 times. Only when its 10. You move it 4 times because of the exponent.
So an easy way to think of this is 10^4 = 10000
10000 * 0.0123
123
See you moved the decimal 4 times to the right.
If it was negative you'd move the decimal left.
It looks like you got the basic gist of it but you need to move the decimal one more time.
