k^4

Answer 1

To simplify \(\frac{k^{120}}{k^{30}}\), you can use the rule of exponents that states \(\frac{a^m}{a^n} = a^{m-n}\).

Applying this rule:

\[
\frac{k^{120}}{k^{30}} = k^{120 - 30} = k^{90}
\]

So, the simplified expression is \(k^{90}\).

Thus, the correct response is **k90** (k to the 90th power).
