Two adjacent corner compensation \(xOy\)  will \(yOy'\) \(=120\) degrees. Calculate  \(\widehat{yOy'}\)

Tìm thương (sorry mk ko bt viết chữ đó ra T.A thế nào)

\(a,\) \(37^5\div37^3\)

\(b,\) \(\left(x+3\right)^7\div\left(x+3\right)^5\)

\(c,\) \(a^{10}\div a^{10}\left(a\ne0\right)\)

\(\left(-3\right)\times\left(-9\right);\left(-6\right)\times\left(+7\right)\)caculated:

two divided two is?
