Question

solve this equation step by step please please please

Answer 1

$\sf{{\dfrac{1}{2}} × 5{\sqrt{2}} × 5{\sqrt{2}}}$

$\sf{\implies {\dfrac{1}{2}} × (5 × 5) × ({\sqrt{2}} × {\sqrt{2}})}$

$\sf{\implies {\dfrac{1}{2} × 25 × {({\sqrt{2}})}^{2}}}$

$\sf{\implies {\dfrac{1}{2}} × 25 × {[{(2)}^{2}]}^{{\frac{1}{2}}}}$

$\sf{\implies {\dfrac{1}{2}} × 25 × {(2)}^{2 × {\frac{1}{2}}}}$

$\sf{\implies {\dfrac{1}{2}} × 25 × {(2)}^{ {\cancel{2}} × {\frac{1}{ {\cancel{2}} }}}}$

$\sf{\implies {\dfrac{1}{2}} × 25 × 2}$

$\sf{\implies {\dfrac{1}{{\cancel{2}}}} × 25 × {\cancel{2}}}$

$\sf\red{\implies 25}$
