Use the properties of exponents to determine whether the equation 10^-1/3=-3√10 is true or false. Select the response that correctly answers the question and provides the appropriate justification.(1 point)

Responses

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

B) True, because the Negative Exponent Rule requires that the number be rewritten as a negative value.

C) 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 .

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

To determine whether the equation \( 10^{-1/3} = -3\sqrt{10} \) is true or false, let's analyze the left side using the properties of exponents.

1. The negative exponent rule states that \( a^{-n} = \frac{1}{a^n} \). Therefore:
\[
10^{-1/3} = \frac{1}{10^{1/3}} = \frac{1}{\sqrt[3]{10}}
\]

2. Now, let’s compare \( \frac{1}{\sqrt[3]{10}} \) to \( -3\sqrt{10} \).

To clarify:
- \( -3\sqrt{10} \) is a negative value.
- \( \frac{1}{\sqrt[3]{10}} \) is a positive value, since it represents the reciprocal of a cube root, which cannot be negative.

Therefore, \( 10^{-1/3} \) cannot be equal to \( -3\sqrt{10} \) since one side is positive and the other is negative.

As a result, the correct response is:

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