{Question}

$\bold{ \red{ {5}^{2} - {4}^{2} + {3}^{2} - {2}^{2} + {1}^{2} }}$

Step 1:-

$\bold{\purple{Simplify \: {5}^{2} \: to \: 25}}$

$\bold{25 - {4}^{2} + {3}^{2} - {2}^{2} + {1}^{2} }$

Step 2:-

$\bold{\purple{Simplify \: {4}^{2} to \: 16}}$

$\bold{25 - 16 + 9 - {2}^{2} + {1}^{2} }$

Step 3:-

$\bold{\purple{Simplify \: {3}^{2} \: to \: 9}}$

$\bold{25 - 16 + 9 - {2}^{2} + {1}^{2} }$

Step 4:-

$\bold{\purple{simplify \: {2}^{2} to \: 4}}$

$\bold{25 - 16 + 9 - 4 + {1}^{2} }$

Step 5:-

$\bold{\purple{Simplify \: {1}^{2} to \: 1}}$

$\bold{25 - 16 + 9 - 4 + 1}$

Step 6:-

$\bold{\purple{Simplify \: 25 - 16 \: to \: 9}}$

$\bold{9 + 9 \: to \: 18}$

Step 7:-

$\bold{\purple{Simplify m9+9 to 18}}$

$\bold{18-4+1}$

Step 8:-

$\bold{\purple{18-4 \: to \: 14}}$

$\bold{14+1}$

Final step: Simplification.

$\bold{\blue\therefore{15}}$
