Resposta:

Olá bom dia!

$a)\\\\5*(6-4)^2-5\\=5*(2)^2-5\\=5*4-5\\=20-5\\=15$

$b)\\\\=(8-5)^2 + 9-4*2\\=(3)^2+9-8\\=9+1\\=10$

$c)\\\\=\frac{6+7*6}{(5+3^3):(12-5*2)} \\=\frac{6+42}{(5+27):(12-10)} \\=\frac{48}{(32):(2)} \\=\frac{48}{16} \\= 3$

$d)\\\\=\frac{(6+7)*6}{(3*6-8:2)-12} \\=\frac{(13)*6}{(18-4)-12} \\=\frac{78}{14-12} \\=\frac{78}{2} \\= 39$
