Answer 1

$a)\\\\(x^5:x^2)~.~(x^7:x^4)\\\\\\(x^{5-2})~.~(x^{7-4})\\\\\\(x^{3})~.~(x^3)\\\\\\x^{3+3}\\\\\\\boxed{x^6}$

$b)\\\\\left(-\dfrac{1}{3}\right)^2~.~\left(-\dfrac{1}{3}\right)^3\\\\\\\left(-\dfrac{1}{3}\right)^{2+3}\\\\\\\boxed{\left(-\dfrac{1}{3}\right)^5}$

$c)\\\\(-0,5)^7~.~(-0,5)~.~(-0,5)^8\\\\\\(-0,5)^7~.~(-0,5)^1~.~(-0,5)^8\\\\\\(-0,5)^{7+1+8}\\\\\\\boxed{(-0,5)^{16}}$
