The expression X^-6 is equivalent to ?

Answer:
[tex]x^{-3}[/tex] × [tex]x^{-3}[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]
Given
[tex]x^{-6}[/tex], then
[tex]x^{-3}[/tex] × [tex]x^{-3}[/tex] = [tex]x^{(-3+(-3))}[/tex] = [tex]x^{(-3-3)}[/tex] = [tex]x^{-6}[/tex]
