Na računalu imamo tipki $\begin{array}{|c|}\hline y^x\\ \hline\end{array}$ in $\begin{array}{|c|}\hline \sqrt[z]{y}\\ \hline\end{array}$. Za sktivacijo druge tipke je običajno treba uporabiti funkcijsko tipko $\begin{array}{|c|}\hline 2nd\\ \hline\end{array}$ ali $\begin{array}{|c|}\hline SHIFT\\ \hline\end{array}$.
Zaporedje tipk je naslednje:
a) $3\begin{array}{|c|}\hline 2nd\\ \hline\end{array}$ $\begin{array}{|c|}\hline y^x\\ \hline\end{array}$ $\begin{array}{|c|}\hline \left(\right.\\ \hline\end{array}$ $4,15$ $\begin{array}{|c|}\hline \cdot\\ \hline\end{array}$ $10 \begin{array}{|c|}\hline y^x\\ \hline\end{array}$ $\begin{array}{|c|}\hline (-)\\ \hline\end{array}$ $3$ $\begin{array}{|c|}\hline \left. \right)\\ \hline\end{array}$ $\begin{array}{|c|}\hline = \\ \hline\end{array}$.
b) $0,25$$\begin{array}{|c|}\hline y^x\\ \hline\end{array}$ $\begin{array}{|c|}\hline \left(\right.\\ \hline\end{array}$ $\begin{array}{|c|}\hline (-)\\ \hline\end{array}$ $3$ $\begin{array}{|c|}\hline :\\ \hline\end{array}$ $4$ $\begin{array}{|c|}\hline\left.\right)\\ \hline\end{array}$ $\begin{array}{|c|}\hline =\\ \hline\end{array}$.
Števila oblike $a\cdot10^n$ lahko vnašamo tudi s tipko $\begin{array}{|c|}\hline {\rm E}\\ \hline\end{array}$ ali tipko $\begin{array}{|c|}\hline {\rm Exp}\\ \hline\end{array}$; npr.: $4,15$ $\begin{array}{|c|}\hline {\rm Exp}\\ \hline\end{array}$ $\begin{array}{|c|}\hline (-)\\ \hline\end{array}$ $3$.

a) $0,16$     b) $2,83$

a) $0,08$  b) Ni realne rešitve (S sosedom predebatiraj, zakaj ni rešitve.)

Poišči na spletu informacijo o tem, kako so definirani koreni sodih stopenj.

Popravi primer b) tako, da bo rešljiv.

$635,024^{-\frac{3}{2}}<\sqrt[7]{0,0365^{-0,4}}<3,241^{\frac{3}{5}}<\sqrt[3]{0,084^{-1}}$

a) $1,31$   b) $0,85$
