Question

The sub-duplicate ratio of $(a+b{)}^2$ : $(a-b{)}^6$ is _________________.

• A. (a + b ) : (a - b)
• B. (a - b) : (a + b)
• C. (a + b) : $(a-b{)}^2$
• D. (a + b) : $(a-b{)}^3$

Answer 1

The correct option is D (a + b) : $(a-b{)}^3$

Sub-duplicate ratio of
$(a+b{)}^2$ : $(a-b{)}^6$
= $\sqrt{(a-b{)}^2}$ : $\sqrt{(a-b{)}^6}$ =
(a + b) : $(a-b{)}^3$
