Question

Find the compounded ratio of (a+b)^2 : (a - b)^2, (a^2 – b^2) : (a^2 + b^2) and (a^4 - b^4) : (a+b)^4​

Answer 1

Answer:

1:1

Step-by-step explanation:

$\frac{(a + b)^{2} }{(a-b)^{2} } * \frac{a^{2} -b^{2} }{a^{2}+ b^{2} } * \frac{a^{4} - b^{4} }{(a+b)^{4} }$

$\frac{(a + b)^{2} }{(a-b)^{2} } * \frac{(a + b)(a -b)}{a^{2}+ b^{2} } * \frac{(a^{2} + b^{2})(a+b)(a-b) }{(a+b)^{4} }$

$\frac{(a + b)^{4} }{(a+b)^{4} \\}$

1/1

so, 1 : 1
