Question

Find the compounded ratio of the following: 

(m-n):(m+n), (m+n)2 : (m2+n2) and (m4 - n4): (m2-n2) 2 

Solution

Compounded ratio of (m-n):(m+n), (m+n)2 : (m2+n2) and (m4 - n4): (m2-n2) 2 

= `("m - n")/("m + n") xx ("m + n")^2/(("m"^2 + "n"^2))` and `("m"^4 - "n"^4)/("m"^2 - "n"^2)^2`


= `("m" - "n")/1 xx ("m + n")/("m"^2 + "n"^2) xx (("m"^2 + "n"^2) ("m"^2 - "n"^2))/("m"^2 - "n"^2)^2`


= `("m"^2 - "n"^2)/("m"^2 + "n"^2) xx (("m"^2 + "n"^2)("m"^2 - "n"^2))/("m"^2 - "n"^2)^2`


= `1/1`

Compounded ratio = 1 : 1 

  Is there an error in this question or solution?
