You find a mutual fund that offers approximately 4% APR compounded
monthly. How much money will you need to invest as a lump sum in order to
have $500 at the end of the year?
O A. $492.31
O B. $507.89
O c. $518.92
O D. $480.40

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.

8.3 and the 3 is repeating

hope this .

i am so sorry , i have no idea but i want points so i won't be a beginner anymore
