To simplify \( 3^{-\frac{178}{-14}} \) using the property of negative integer exponents, we first simplify the exponent \(-\frac{178}{-14}\).
-
Simplifying the fraction: \[ -\frac{178}{-14} = \frac{178}{14} \]
-
Next, we can simplify \(\frac{178}{14}\):
- \(178\) and \(14\) can both be simplified by \(2\): \[ \frac{178 \div 2}{14 \div 2} = \frac{89}{7} \]
-
Now we rewrite the expression with the positive exponent: \[ 3^{-\frac{178}{-14}} = 3^{\frac{89}{7}} \]
Thus, the expression equivalent to \( 3^{-\frac{178}{-14}} \) with positive exponents only is:
\[ 3^{\frac{89}{7}} \]
