h, before you answer my question, i just wanted to remind you to drink some water and do things that make you happy. the pandemic has effected us all differently, so if you can, take a walk, stretch for a bit, and remind yourself that you belong and that you are needed! ✧･ﾟ: *✧･ﾟ:* ʕ·ᴥ·ʔ ʕ•ᴥ•ʔ *:･ﾟ✧*:･ﾟ✧ anyways, what is two plus two?

Yeah I feel like lately I've been overdoing it a bit. I've been playing video games way longer then I used too, then again I have nothing better to do, but it's time I start taking a little more care of my body. Thanks for the nice words!  2+2 = 4.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

never fear papaguy is here
