Solution 1.3:1a
From Förberedande kurs i matematik 1
We calculate \displaystyle 2^{3} first and then \displaystyle 3^{2}
\displaystyle \begin{align} & 2^{3}=2\centerdot 2\centerdot 2=4\centerdot 2=8, \\ & \\ & 3^{2}=3\centerdot 3=9 \\ \end{align}
Hence,
\displaystyle 2^{3}\centerdot 3^{2}=8\centerdot 9=72
