Question 631395
Whoa there... x in this case is a variable, not a multiply sign.
----------------------------
The original thing you need to simplify is:
{{{((8x)^-7)((8x)^3))}}}
----------------------------
You can rewrite anything raised to a negative power as it's inverse raised to the positive power. For example:
{{{(8x)^-7}}} is the same as {{{1/(8x)^7}}}
------------------------------
Using this principle, you can rewrite your given expression as:
{{{(8x)^3/(8x)^7}}}
------------------------------
You can now simplify the above by cancelling:
{{{highlight(1/(8x)^4)}}}
