Answer:
a = $12,600
Step-by-step explanation:
Formula for Compound interest :
a = Amount
p = Initial Principal
r = Interest rate per annum
n = number of years
a = 10,000 * (1.26)
6.85
By AAS axiom
2560000
2.56 x 10⁶
Since the exponent is positive 6, you can "move" the decimal place 6 times to the right.
Put in a bunch of 0's so you don't get lost:
2.56000000000000
Move 6 over -->>
0.42
