Объяснение:

по свойствам степеней:

Показатели степеней с одинаковым основанием при умножении складываются!

При делении- вычитаются!

Значит:

x^{40}= x^{9}*x^{*}*x^{23}; 40=9+*+23;\\*=40-9-23;\\*=8

a^**a^5*a^{23}=a^{41};\\*+5+23=41;\\*+28=41;\\*=41-28=13;\\

(ad)^**(ad)*(ad)^9=(ad)^{14}\\*+1+9=14\\*=14-10\\*=4;\\

(\frac{c}{4} )^{20}*(\frac{c}{4} )^{*}=(\frac{c}{4} )*(\frac{c}{4} )^{25};\\20+*=1+25;\\20+*=26;\\*=26-20=6;\\\\

(\frac{k}{3})^{20} =(\frac{k}{3})^{10} *(\frac{k}{3})^{*} ;\\20=10+*;\\*=20-10=10;\\\\

(1,3t)^*:(1,3t)^{8}=(1,3t)^{13};\\*-8=13;\\*=13+8=21;\\

1)      x^{40}=x^{9} *x^{*} *x^{23}

       x^{40}=x^{9+*+23}

        *=40-32

       *=8

Ответ:   x^{40}=x^{9} *x^{8} *x^{23}

2)    a^{*}*a^{5} *a^{23} =a^{41}

     *=41-5-23

     *=13

Ответ:   a^{13}*a^{5} *a^{23} =a^{41}

3)   (ad)^{*} *(ad)^{} *(ad)^{9} =(ad)^{14}

       *=14-1-9

      *=4

Ответ:  (ad)^{4} *(ad)^{} *(ad)^{9} =(ad)^{14}

4)     (\frac{c}{4})^{20}*  (\frac{c}{4})^{*}= (\frac{c}{4})^{}  * (\frac{c}{4})^{25}

       20+*=1+25

       *=26-20

       *=6

Ответ:   (\frac{c}{4})^{20}*  (\frac{c}{4})^{6}= (\frac{c}{4})^{}  * (\frac{c}{4})^{25}

5)  (\frac{k}{3})^{20}= (\frac{k}{3})^{10}  * (\frac{k}{3})^{*}

   *=20-10

    *=10

Ответ:    (\frac{k}{3})^{20}= (\frac{k}{3})^{10}  * (\frac{k}{3})^{10}

6)   (1,3)^{*}: (1,3)^{8} =(1,3)^{13}

     *-8=13

     *=13+8

     *=21

Ответ:  (1,3)^{21}: (1,3)^{8} =(1,3)^{13}
