To determine how many times less 102 is than 106, we can calculate the ratio of the two numbers:
\[ \frac{102}{106}. \]
Now, simplifying this fraction:
\[ \frac{102}{106} = \frac{102 \div 106}{106 \div 106} = \frac{102}{106} = 0.9622641509433962 \text{ (approximately)}. \]
Next, we want to express how many times less 102 is than 106 in terms of an integer power of 10.
To find how many times less 102 is than 106, we can look at the difference:
\[ 106 - 102 = 4. \]
However, rewriting the ratio in terms of a fraction of 106 gives:
\[ \frac{102}{106} = 1 - \frac{4}{106} \approx 1 - 0.0377358490. \]
Relative to 106, we consider how much smaller 102 is, implying we should focus more on the representation as a value less than 1:
\[ \frac{106}{102} = \frac{106 \div 102}{102 \div 102} = \frac{106}{102} \approx 1.0392156862655365. \]
Now, we approximate how this relates to the power of 10.
To express this accurately as an integer power of 10, we can approximate \( \frac{102}{106} \) as \( 0.0001 = 10^{-4}\).
Thus, the answer is:
\[ \text{The final answer is } 10^{-4}. \]
