Answer 2

Answer:

$\huge \red{\frac{ {a}^{2} }{ {b}^{2} } + \frac{2 {b}^{2} }{ {a}^{2} } }$

$\huge \boxed{lcm : {a}^{2} {b}^{2} }$

$\huge \green{\frac{ {a}^{2} }{ {b}^{2} } \times \frac{ {a}^{2} }{ {a}^{2} } + \frac{2 {b}^{2} }{ {a}^{2} } \times \frac{ {b}^{2} }{ {b}^{2} } }$

$\huge \red{= \frac{ {a}^{4} + 2 {b}^{4} }{ {a}^{2} {b}^{2} } }$

$\huge\boxed{ \frac{ {a}^{4} + {2b}^{4} }{ {a}^{2} {b}^{2} } }$
