3x+x+20 = 180
4x = 180-20
4x = 160
x = 40

×+20+3x+2x+38+C=360
40+20+3×40+2×40+38+C=360
40+20+120+80+38+C=360
298+C=360
C=360-298
C =62°

Cube root of - 1000p^12q^3

aleksley [76]

$\bf \sqrt[3]{-1000p^{12}q^3}~~
\begin{cases}
1000=10^3\\
(-1)^3=-1\cdot -1\cdot -1\\
\qquad -1\\
p^{12}=p^{4\cdot 3}\\
\qquad (p^4)^3
\end{cases}\implies \sqrt[3]{(-1)^3(10)^3(p^4)^3q^3}
\\\\\\
(-1)(10)p^4q\implies -10p^4q$
