Answer 2

$\huge{\red{\underline{\overline{ᴀ}}}}{\color{orange}{\underline{\overline{ɴ}}}}{\color{gold}{\underline{\overline{s}}}}{\color{green}{\underline{\overline{ᴡ}}}}{\blue{\underline{\overline{ᴇ}}}}{\pink{\underline{\overline{ʀ}}}}\star$

$\bull \: \: \: \: \: \: \bold{ \red{ \underline{ \underline {\green{1) \: 10 {b}^{2} }}}}}$

Step-by-step explanation:

Given :

$\sf where \begin{cases} & \sf{ { \: \: \: 4a}^{2} + 5 {b}^{2} } \\ \\ & \sf{ - {4a}^{2} + {5b}^{2} } \end{cases}$

To Find :

• the addition

Solution :

__________________________________________

$\\ \dashrightarrow \sf ({4a}^{2} + 5 {b}^{2} ) + ( - {4a}^{2} + 5 {b}^{2} )$

$\\ \dashrightarrow \sf \cancel{4 {a}^{2} } + 5 {b}^{2} - \cancel{4 {a}^{2}} + 5 {b}^{2}$

$\\ \dashrightarrow \sf{5b}^{2} + 5 {b}^{2}$

$\\ \dashrightarrow \underline{\boxed{ \frak{ \purple{10 {b}^{2} }}}} \star$

$\underline{ \text{Therefore, the value of addition is (option a)10b²}}$
