The question asks to find the value of \( P \), given that:

\[
P_8 = 1010110101_2
\]

This notation means that \( P_8 \) is the base-8 representation of the binary number \( 1010110101_2 \). To solve this, we need to first convert the binary number \( 1010110101_2 \) to decimal, and then interpret that as an octal (base-8) number.

### Step 1: Convert binary \( 1010110101_2 \) to decimal.
The binary number \( 1010110101_2 \) can be expanded as:

\[
1010110101_2 = 1 \cdot 2^9 + 0 \cdot 2^8 + 1 \cdot 2^7 + 0 \cdot 2^6 + 1 \cdot 2^5 + 1 \cdot 2^4 + 0 \cdot 2^3 + 1 \cdot 2^2 + 0 \cdot 2^1 + 1 \cdot 2^0
\]

Now, compute the powers of 2 and add them:

\[
= 512 + 0 + 128 + 0 + 32 + 16 + 0 + 4 + 0 + 1 = 693
\]

So, \( 1010110101_2 \) in decimal is 693.

### Step 2: Interpret 693 as a base-8 number \( P_8 \).

Now, we need to convert the decimal number 693 from base-8 to base-10.

The base-8 number 693 can be expanded as:

\[
693_8 = 6 \cdot 8^2 + 9 \cdot 8^1 + 3 \cdot 8^0
\]

Calculating each term:

\[
6 \cdot 8^2 = 6 \cdot 64 = 384
\]
\[
9 \cdot 8^1 = 9 \cdot 8 = 72
\]
\[
3 \cdot 8^0 = 3 \cdot 1 = 3
\]

Adding these together:

\[
384 + 72 + 3 = 459
\]

Thus, \( P = 459 \).
