Question

“Rewrite the following expression so there are no negative exponents. Do not simplify”

Answer 1

The rule of the negative exponent is given below:

$X^{-a}=\frac{1}{X^a}$

Hence, the expression:

$\frac{yx^3.-2x^{-2}y^{-2}}{-3x^{-1}y^{-4}.-3y^3}$

can then be re-written, without the negative exponent, as:

$\frac{yx^3\text{ . }\frac{-2}{x}\frac{1}{y^2}}{\frac{-3}{x}\frac{1}{y^4}.-3y^3}$

2) The expression:

$\begin{gathered} \frac{x^3y^{-1}}{3x^4y^{-2}.2x^2y^2} \\ \end{gathered}$

can be re-written, without the negative exponent, as:

$\frac{x^3\times\frac{1}{y}^{}}{3x^4\times\frac{1}{y^2}.2x^2y^2}$
