{2x+10 = x + 10
{y = x + 5

{2x - x = 10 - 10

Describe how (2 cubed) (2 superscript negative 4) can be simplified.
Varvara68 [4.7K]

<u>Given</u>:

The given expression is (2^3)(2^{-4})

We need to determine how the expression can be simplified.

<u>Simplifying the expression:</u>

Let us determine how the expression can be simplified.

The expression is given by

(2^3)(2^{-4})

Applying the exponent rule that a^{b} \cdot a^{c}=a^{b+c} in the above expression, we get;

2^{3} \cdot 2^{-4}=2^{3-4}

Adding the exponents, we get;

2^{3} \cdot 2^{-4}=2^{-1}

Again, applying the exponent rule a^{-1}=\frac{1}{a}, we get;

2^{3} \cdot 2^{-4}=\frac{1}{2}

Thus, the simplified expression is \frac{1}{2}

Hence, the expression is simplified by adding the exponents and keep the same base. Then find the reciprocal and change the sign of the exponent.

Therefore, Option D is the correct answer.
