x^(-5)*x^4

To solve this expression, we can use the rule of exponents that states when you multiply two exponents with the same base, you add the exponents. In this case, we have x raised to the power of -5 multiplied by x raised to the power of 4.

When multiplying two exponents with the same base, we add the exponents:
x^(-5) * x^4 = x^(-5+4) = x^(-1)

So, x^(-5) * x^4 simplifies to x^(-1).
