Răspuns: Ai rezolvarea mai jos

Explicație pas cu pas:

$\bf \big(2005\cdot 2006+2004\cdot2005\big)^{2}=$

$\bf \big[2005\cdot\big(2006+2004\big)\big]^{2}=$

$\bf \big(2005\cdot4010\big)^{2}=\big(2005\cdot2\cdot2005\big)^{2}=$

$\bf \big(2005^{1+1}\cdot2\big)^{2}=\big(2005^{2}\cdot2\big)^{2}=$

$\bf 2005^{2\cdot2}\cdot2^{2}=\red{\underline{~2005^{4}\cdot2^{2}~} }$
