    Not that you can rewrite that as 4.8 * 10^(-6) V = 4.8 "x"V.

    Now what x can you think of that makes 4.8 xV = 4.8 * 10^(-6) V?

    If you had 4.8 * 10^(-9) V you'd use 4.8 \muV for nano. In this case, it's...?

    wouldnt you use n for nano as it equals 10^-9? instead of \mu as it equals 10^-6

    Oh yeah, my bad.

    And my previous post was wrong btw, I misread the question. It's 4.8 * 10^(-5). So change it to 48 * 10^(-6) V.

    But you know that 10^(-6) V is the same as a micro Volt. So you can write it as 48 \, \,\mu V
