False, because according to the Negative Exponent Rule, the equation should be 10−13=−110√3
.
False, because according to the Negative Exponent Rule, the equation should be 10 superscript negative Start Fraction 1 over 3 End Fraction baseline equals negative Start Fraction 1 over root index 3 Start Root 10 End Root End Fraction .

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

True, because the negative sign moves to the front when writing an equivalent expression.

To determine whether the equation \( 10^{-13} = -10^{-\sqrt{3}} \) is true or false, we can analyze both sides.

  1. Left Side: \[ 10^{-13} = \frac{1}{10^{13}} \] This is a standard application of the negative exponent rule.

  2. Right Side: \[ -10^{-\sqrt{3}} = -\frac{1}{10^{\sqrt{3}}} \] Again, applying the negative exponent rule, we rewrite \( 10^{-\sqrt{3}} \).

Now we will compare both sides:

  • The left side \( \frac{1}{10^{13}} \) represents a positive value because it is the reciprocal of a positive number.
  • The right side \( -\frac{1}{10^{\sqrt{3}}} \) is negative because it is the negative of a positive value.

Since one side is positive and the other side is negative, we can conclude that:

False, because the left side is positive while the right side is negative, making them unequal.

Among the provided options, the closest correct response would be:

False, because according to the Negative Exponent Rule, the equation should be \( 10^{-13} = -\frac{1}{10^{\sqrt{3}}} \).

Please choose the response that aligns most closely with this explanation.
