Question

Examine Tamika’s work below. What is Tamika’s error?

Answer 1

Answer:

(A)

Step-by-step explanation:

Tamika's work is wrong as:

The given equation is:

$\frac{18a^{-5}b^{-6}}{30a^3b^{-5}}$

She added the components, while the components must be subtracted in this equation, thus the equation becomes

=$\frac{3a^{-5}a^{-3}b^{-6}b^5}{5}$

=$\frac{3a^{-8}b^{-1}}{5}$

=$\frac{3}{5a^8b}$

which is the required simplified form.

Thus, the option A is correct.

Answer 2

The answer would be A. adding the exponents
