Multiply or divide as indicated. x^-8 • x^-2
gladu [14]

ANSWER

\frac{1}{ {x}^{10} }

EXPLANATION

The given exponentiial expression is

{x}^{ - 8}  \bullet {x}^{ - 2}

We simplify using the rule:

{a}^{m}  \times  {a}^{n}  =  {a}^{m + n}

We apply this property to get:

{x}^{ - 8}  \bullet {x}^{ - 2}  = {x}^{  - 8 + - 2}

We simplify to get;

{x}^{ - 8}  \bullet {x}^{ - 2}  = {x}^{  - 10}

We rewrite as a positive index to get;

{x}^{ - 8}  \bullet {x}^{ - 2}  =  \frac{1}{ {x}^{10} }
