Question

Responde pra mim (a^2+5m)^2

Answer 1

Quadrado da diferença:

$\mathsf{\left(a-b\right)^2=a^2-2ab+b^2}$

Resolvendo:

$\mathsf{\left(a^2-5m\right)^2}\\\mathsf{\left(a^2\right)^2-\left(2\cdot a^2\cdot 5m\right)+\left(5m\right)^2}\\\mathsf{a^{\left(2\cdot 2\right)}-10a^2m+5^2m^2}\\\boxed{\mathsf{a^4-10a^2m+25m^2}}$
