Question

Tuna simplified the expression 3x^3/12x^-2 to x/4 what was tryna mistake?

Answer 1

Answer:

She added the exponents instead of subtracting them.

Step-by-step explanation:

She was to simplify:

$\frac{3x^3}{12x^-^2}$

Dividing the numerator with 3 and the denominator with three gives:

$\frac{x^3}{4x^-^2}$

Then, x³ ÷ $x^{-2}$ would be $x^{3 - -2}$ = $x^{5}$

(Where there is division; we are supposed to subtract the exponents.)

So the final answer would be: $\frac{x^5}{4}$
