Answer 13

Solve x2 = −169.

Answer 14

\[x^{3}=\frac{ 64 }{ 27 } \rightarrow \sqrt[3]{x^{3}}=\sqrt[3]{\frac{ 64 }{ 27 }} \rightarrow x=\frac{ \sqrt[3]{64} }{ \sqrt[3]{27} } \rightarrow x=\frac{ 4 }{ 3 }\]

Answer 16

You can use a calculator for direct answers. That isn't fun though.
\[x ^{2}=-169\] is tricky because you can't multiply anything by itself and get a negative number. Mathematicians like to play pretend though so they made up and imaginary number and called it i
\[i==-1\]
That makes your problem
\[x=(\sqrt{169})i\]
