Five years ago gary invested $10,000 into an account that makes 6% compounded annually. the value in the account after x years is represented by the formula v = 10,000(1.06)x. assuming that gary has made no deposits or withdrawals, how much money is in the account now? a) $11,583.46 b) $12,624.77 c) $13,382.26 d) $14,185.19

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.
