Tyna simplified the expression 3x^3/12x^-2 to x/4. What was Tyna’s mistake?

Ksenya-84 [330]

We are given expression: $\frac{3x^3}{12x^{-2}}$ .

Tyna simplified the given expression to $\frac{x}{4}$ .

Explanation: In order to simplify $\frac{3x^3}{12x^{-2}}$ , Tyna need to simplify rational expression $\frac{3}{12}$ .

On dividing top and bottom by 3, we get $\frac{1}{4}$ .

Which Tyna got correct.

Now she need to simplify $\frac{x^3}{x^{-2}}$ .

<em>On applying quotient rule of exponents, we need to subtract the exponents of x's.</em>

So, it would be $\frac{x^3}{y^-{2}} = x^3-{-2} = x^{3+2} = x^5$ .

<h3>So, the final answer should be $\frac{x^5}{4}$ .</h3><h3>Therefore, Tyan forgot to add exponent to x.</h3><h3>The exponent of x should be 5.</h3>
