If `2a+b+3c=1a n da >0,b >0,c >0,` then the greatest value of `a^4b^2c^2` is `1/(9. 4^8)` b. `1/(9. 4^5)` c. `1/(9^4 .4^8)` d. `1/(9^4 .4^)`

If 2a+b+3c=1 and a>0,b>0,c>0 then the greatest value of a^(4)b^(2)c^(2) is (1)/(9.4^(8)) b.(1)/(9.4^(5)) c.(1)/(9^(4).4^(8)) d.(1)/(9^(4).4)

If a+b+c=0a n da^2+b^2+c^2=1, then the value of a^4+b^4+c^4 is 1 b. 4 c. 1/2 d. 1/4

If a+b+c=0 and a^(2)+b^(2)+c^(2)=1, then the value of a^(4)+b^(4)+c^(4) is 1 b.4 c.(1)/(2) d.(1)/(4)

The minimum value of 2x^2 +x-1 is: a) -1/4 b) 3/2 c) -9/8 d) 9/4

Find the value of (2/3)^2 a) 4/9 b) 9/4 c) -2/9 d)0

If a : b=4:5 and b : c=2:3, then a : c (a) 4:3 (b) 8: 15 (c) 8:9 (d) 5:3

If A : B : C=2:3:4, then the ratio A/B : B/C : C/A is equal to 4:9: 16 b. 8:9: 24 c. 8:9: 12 d. 8:9: 16

If a digit is chosen at random from the digits 1,2,3,4,5,6,7,8,9, then the probability that it is odd,is (4)/(9)( b) (5)/(9)(c)(1)/(9)(d)(2)/(3)

If A=[(0, 4, 9), (8, 3, 7)], B=[(7, 3, 8), (1, 4, 9)] find the value of 3A-9B
