Problem: If x:y=3:4, find the value of x^(2)y xy^(2):x^(3) y^(3).
Solution:
Given, x:y=3:4
Let us assume x=3k and y=4k where k is a constant.
Now, we need to find the value of x^(2)y xy^(2):x^(3) y^(3).
So, substituting the values of x and y, we get
x^(2)y xy^(2):x^(3) y^(3) = (3k)^(2) x (4k) x (4k)^(2):(3k)^(3) x (4k)^(3)
= 36k^(3) x 64k^(3):27k^(3) x 64k^(3)
= 2304:11664
= 4:13
Therefore, the value of x^(2)y xy^(2):x^(3) y^(3) is 4:13.
Hence, the correct answer is option (b) 12:13.
Answer: (b) 12:13
Solution:
Given, x:y=3:4
Let us assume x=3k and y=4k where k is a constant.
Now, we need to find the value of x^(2)y xy^(2):x^(3) y^(3).
So, substituting the values of x and y, we get
x^(2)y xy^(2):x^(3) y^(3) = (3k)^(2) x (4k) x (4k)^(2):(3k)^(3) x (4k)^(3)
= 36k^(3) x 64k^(3):27k^(3) x 64k^(3)
= 2304:11664
= 4:13
Therefore, the value of x^(2)y xy^(2):x^(3) y^(3) is 4:13.
Hence, the correct answer is option (b) 12:13.
Answer: (b) 12:13
