" 6."x^(6)-729

Factorize the following expressions x^6- 729

(2 + 5 omega + 2 omega ^ (2)) ^ (6) = (2 + 2 omega + 5 omega ^ (2)) ^ (6) = 729

Factorise : 64x^3-729y^3

6x^(2)+5x-6

If the mean and variance of a binomial variate X are 7/3a n d(14)/9 respectively. Then probability that X takes values 6 or 7 is equal to 1/(729) 2. 5/(729) 3. 7/(729) 4. (13)/(729) 5. (15)/(729)

If 6^(x-y)=36 and 3^(x+y)=729 , then find x^(2)-y^(2) .

The following steps are involved in finding the value of 3^(n-3) , when 3^n=729 . Arrange them in seqential order. (A) 3^(n-3)=3^(6-3)=3^3=27 (B) rArrn=6 (C) 3^(n)=729rArr3^n=3^6
