Answer:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
Step-by-step explanation:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
To prove this conjecture
unit digit = 6
hence the property is true for ; n = 1 and n = 2 and also for every odd and even number ( i.e. from 1 to 8 )
we have f(x)=15.2^x we have f(6)=960
It means we at x=6 the population of frog is 960 where the x is meant for sixth week .
so the correct option is D )the number of weeks that have passed
Answer: An article was sold at a 20% discount, at Rs. 400. What was its marked price?
Let M denotes the required marked price of the given article.
Hence from above data we get following relation,
(1 - 20/100)*M = 400
or (4/5)*M = 400
or M = (5/4)*400 = 500 (Rs) [Ans]

Answer:
The steps are more or less the same, except for one new addition:
1. Divide the tens column dividend by the divisor.
2. Multiply the divisor by the quotient in the tens place column.
3. Subtract the product from the divisor.
4. Bring down the dividend in the one's column and repeat it.
