Question

Se X = - 4 , Y = - 2 , Z = - 7 , A = 1 , calcule A. X. Y. Z *​

Answer 1

Vamos lá!

A . X . Y . Z =

1 . - 4 . - 2 . - 7 =

- 4 . 14 =

$\blue{\boxed{\boxed{= - 56}}}$

Answer 2

$\Large\boxed{\begin{array}{l}\rm Se~X=-4,Y=-2,Z=-7,A=1,calcule\\\rm A\cdot X\cdot Y\cdot Z.\\\underline{\rm soluc_{\!\!,}\tilde ao:}\\\sf substituindo~as~letras~pelos~seus~respectivos\\\sf valores~temos:\\\sf 1\cdot(-4)\cdot(-2)\cdot(-7)=-56\\\sf A\cdot X\cdot Y\cdot Z\bigg|_{A=1~X=-4~Y=-2~Z=-7}=-56\end{array}}$
