Question

The square of (-abc) is

Answer 1

It is read as a minus b minus c whole square. The (a - b - c)2 formula is expressed as (a - b - c)2 = a2 + b2 + c2 - 2ab + 2bc - 2ca.

Answer 2

We know

• (ab)^m=a^mb^m

Now

$\\ \sf\longmapsto (-abc)^2$

$\\ \sf\longmapsto (-abc)(-abc)$

$\\ \sf\longmapsto (-a)^2(b)^2(c)^2$

$\\ \sf\longmapsto a^2+b^2+c^2$
