Answer:
Colin will have 421824 pennies after 2 years
Step-by-step explanation:
Given:
Amount invested in bank by Colin (P) = £3900
Rate of interest (r) = 4%
Time period (n) = 2 years
To find: Amount after 2 years (A)
Solution:
Formula for amount (A) is 

As 1 pound = 100 pennies,
4218.24 pounds = 4218.24 × 100 = 421824 pennies
So,
Colin will have 421824 pennies after 2 years.

Note that both the numerator and denominator approach 0 as

, so we can try using L'Hopital's rule.

The denominator is nonzero at

, so the limit is equivalent to
76% of 200<span> = </span><span>152</span>76/100 * 200
<span>
= 76*200/ 100 = 152</span>
If 4=2^2
8=2^3
(2^)2x+10=(2^)6x
(2^)6x-(2^)2x=10
(2^)2x×7=10, where x has no real value
