To solve the expression \( 7^{-8} \times 7^{-7} \), we can use the property of exponents which states that when multiplying two powers with the same base, we add the exponents.
So, we have:
\[
7^{-8} \times 7^{-7} = 7^{-8 + (-7)} = 7^{-15}
\]
The final answer is:
\[
7^{-15}
\]
If you want to express this without the negative exponent, it can be written as:
\[
\frac{1}{7^{15}}
\]
So, we have:
\[
7^{-8} \times 7^{-7} = 7^{-8 + (-7)} = 7^{-15}
