1.sederhanakanlah

Jawab:

$a. :3^{5} times 3^{2} \= 3^{(5+2)} \= 3^{7} \\b. :(-7)^{7} times(-7)^{5}\= (-7)^{(7+5)} \= (-7)^{12} \\c.:y^{2} times y^{5} \= y^{(2+5)} \= y^7\\d. : p^5times p^3 times p^2\= p^{(5+3+2)}\= p^{10}$

Sifat-sifat bilangan berpangkat positif :

$a^m times a^n = a^{m+n}$
$a^m:a^n=a^{m-n}, m>n :$
$(a^m)^n = a ^{(m times n)}$
$(ab)^m = a^mb^m$
$(frac{x}{y} )^m= frac{a^m}{b^m} , b neq 0$
