Slide 8 - Tekstslide

Shorten expressions - with letters

a^{​ 2 ​ ​} = a \cdot a

a^{​ 3 ​ ​} = a \cdot a \cdot a

a^{​ 7 ​ ​} = a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a

a^{​ 12 ​ ​} = a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a

a^{​ 49 ​ ​} = a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a \cdot a =

Slide 9 - Tekstslide

Shorten expressions - with letters

a^{​ 2 ​ ​} = a \cdot a

a^{​ 2 ​ ​} b = a \cdot a \cdot b

a^{​ 4 ​ ​} b^{​ 3 ​ ​} = a \cdot a \cdot b \cdot b \cdot b \cdot a \cdot a

a^{​ 8 ​ ​} b^{​ 4 ​ ​} = a \cdot a \cdot a \cdot a \cdot b \cdot a \cdot b \cdot a \cdot b \cdot a \cdot b \cdot a

a^{​ 30 ​ ​} b^{​ 19 ​ ​} = b \cdot a \cdot b \cdot a \cdot b \cdot b \cdot a \cdot a \cdot b \cdot a \cdot a \cdot b \cdot a \cdot b \cdot a \cdot a \cdot b \cdot a \cdot a \cdot b \cdot a \cdot b \cdot a \cdot a \cdot b \cdot a \cdot a \cdot a \cdot b \cdot a \cdot a \cdot a \cdot a \cdot a \cdot b \cdot a \cdot a \cdot b \cdot b \cdot a \cdot a \cdot a \cdot b \cdot a \cdot a \cdot a \cdot b \cdot a

Slide 30 - Tekstslide

What do you think?

\frac{​ a ^{​ 4 ​ ​} ​ ​}{​ a ^{​ 2 ​ ​} ​} = a^{​ 4 - 2 ​ ​} = a^{​ 2 ​ ​}

\frac{​ a ^{​ 4 ​ ​} b ^{​ 4 ​ ​} ​ ​}{​ a ^{​ 3 ​ ​} b ​} = a^{​ 4 - 3 ​ ​} \cdot b^{​ 4 - 1 ​ ​} = a b^{​ 3 ​ ​}
