Answer 1

$\Box \ \ \boxed{\begin{array}{l}\sf a) \ (-1)^3 \ ?? \end{array}}\\\\\Box \ \ \boxed{\begin{array}{l}\sf -1 \ . \ -1 \ . \ -1 =-1 \end{array}}\\\\=\\\\\Box \ \ \boxed{\begin{array}{l}\sf b) \ 8^6 \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf 8 \ . \ 8 \ . \ 8 \ . \ 8 \ . \ 8 \ . \ 8=262144 \end{array}}\\\\=\\\\\Box \ \ \boxed{\begin{array}{l}\sf c)1^3 \end{array}}\\\\\Box \ \ \boxed{\begin{array}{l}\sf 1 \ . \ 1 \ .\ 1=1 \end{array}}\\\\=\\\\\Box \ \ \boxed{\begin{array}{l}\sf d)6^1 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf 6 \ . = 6\end{array}}\\\\=\\\\\Box \ \ \boxed{\begin{array}{l}\sf e) \ 10^8 \end{array}}\\\\\\\Box \ \ \boxed{\begin{array}{l}\sf 10^8=10 \ . \ 10 \ . \ 10 \ . \ 10 \ . \ 10 \ . \ 10 \ . \ 10 \ . \ 10=100.000.000 \end{array}}\\\\=$
