# How do you simplify 4yx^-1 and write it using only positive exponents?

Aug 25, 2016

$\frac{4 y}{x}$
Anything raised to a negative power just means that that something is the denominator of a fraction, so: ${x}^{-} 2 = \frac{1}{x} ^ 2$
Assuming that the only thing being raised to $- 1$ in your question is $x$, we then have:
$4 y \cdot \frac{1}{x}$ or $\frac{4 y}{x}$
