Solve (1+x)(1+y) / (1-x)(1-y) ?

Hi Maadhu,Can you please elaborate the questions as in what specific form the answer needs to be?

n is a number such that 2n has 28 factors and 3n has 30 factors,then 6n has how many factors

Hi Neha,here,for 2n, 28 = 7*4for 3n,30= 6*5 Hence, one factor of n should be 2 raised to the power of 5. the other factor is 3 raised to the power of 3.When n is multiplied by 6Number of factors of 6n = 7*5 = 35Thanks,Varun.

Find the remainder when 10^10+ 10^100+ 101^000 + . . . +10^10000000000 is divided by 7.

All you need is basic modular arithmetic. No totient rule needed. Since 10 is congruent to 3 (Mod 7), 10^10 is congruent to 3^10 (mod 7). 3^10 = 9^5, which is congruent to 2^5 = 32 (mod 7). When we divide 32 by 7, we get a remainder of 4. Therefore, 10^10 is congruent to 4 (mod 7). In order to find what 10^100 is congruent to mod 7, we raise both sides of the previous equation by the power of 10 to get (10^10)^10 = 4^10 (mod 7). 4^10 = 16^5 (mod 7), which is congruent to 2^5 (mod 7). We know that 10^100 is congruent to 4 mod 7. Repeating this process of taking the power of 10, we discover that each term in the series has remainder 4 mod 7. There are 10 terms in the series, which adds up to a sum of 10*4 = 40, which is congruent to 5 mod 7. ANSWER: 5

first we reduce it to : (3^10+3^100+....+3^10000000000)/7 Apply totient rule each term, -> 3^4+3^4+....+3^4(10 terms)/7 [totient of 7=6 and remainder of power of 10 divided by 6 is always 4]=remainder(81*10/7)= (4*3)/7= 5 answer

find the value of the expression 1+4 division 3*9 of (6-2) the ns is 49 but i didnt understood the way u solved Akhilesh Sir

1+4/3*9 of (6-2) 1+4/3* 9*4 1+4/3* 36 if we divide 4 by 3 then we get 1.3333333333 multiply 1.3333333333*36 we get 48 1+ 1.3333333333 * 36 1+48 49.

We simply have to follow the BODMAS rule, so bracket will be solved first, after solving the bracket the equation becomes1+4 div 3*9of 4After bracket comes of, so solving of,we get 1+ 4div 3*36Now we will solve division so we get,1 + 4/3*36 => 1+48 = 49Hope it is clear now.
