Question

-13 x elevado a 3 y mais 6 x elevado a 3 y =

Answer 1

$\left(-13x\right)^{3y}+\left(6x\right)^{\:3y} \quad : \quad como\;\;\left(a\cdot \:b\right)^n=a^nb^n\\\\ = 13^{3y}x^{3y}+6^{3y}x^{3y}\quad : \quad como\;\;a^{bx}=\left(a^b\right)^x\\\\ =\left(13^3\right)^y+ \left(6^3\right)^y\\\\ =2197^yx^{3y}+216^yx^{3y}$
