To determine whether the equation \( 10^{-13} = -10^{-\frac{1}{3}} \) is true or false, let's analyze both sides:

  1. Left Side: \[ 10^{-13} = \frac{1}{10^{13}} \]

  2. Right Side: \[ -10^{-\frac{1}{3}} = -\frac{1}{10^{\frac{1}{3}}} = -\frac{1}{\sqrt[3]{10}} \]

Now let’s simplify the expressions:

  • The left side \( 10^{-13} \) is a very small positive number (since it represents \( \frac{1}{10^{13}} \)).
  • The right side \( -10^{-\frac{1}{3}} \) is a negative number (since it represents \( -\frac{1}{\sqrt[3]{10}} \)).

Since one side is positive and the other side is negative, the two sides cannot be equal.

Thus, the equation \( 10^{-13} = -10^{-\frac{1}{3}} \) is false.

Now, let’s look at the response options. The one that correctly answers the question and provides appropriate justification is:

False, because the Negative Exponent Rule requires that the number be rewritten as a quotient, not as a negative value.

This is indeed correct, but the key justification here is more about understanding that one side is positive and the other side is negative, which is the main reason they cannot be equal.
