Ratio and Proportions
If a: b = b: c, then ratio \( \Large a^{4}:b^{4} \) is equal to
A) ac : \( \Large b^{2} \)
B) \( \Large a^{2}:c^{2} \)
C) \( \Large c^{2}:a^{2} \)
D) \( \Large b^{2} \) : ac
Correct Answer:
B) \( \Large a^{2}:c^{2} \)
Description for Correct answer:
Given that, a/b = b/c => \( \Large b^{2} \)=ac
\( \Large a^{4}:b^{4}=a^{4}:a^{2}c^{2}=a^{2}:c^{2} \)
