Convert 1110010101 to hindu arabic numbers

To convert the binary number **1110010101** to a Hindu-Arabic number (decimal), follow these steps:

1. Start by writing the binary digits with their corresponding powers of 2:
   \[
   1 \cdot 2^{9} + 1 \cdot 2^{8} + 1 \cdot 2^{7} + 0 \cdot 2^{6} + 0 \cdot 2^{5} + 1 \cdot 2^{4} + 0 \cdot 2^{3} + 1 \cdot 2^{2} + 0 \cdot 2^{1} + 1 \cdot 2^{0}
   \]

2. Calculate the values:
   \[
   (1 \cdot 512) + (1 \cdot 256) + (1 \cdot 128) + (0 \cdot 64) + (0 \cdot 32) + (1 \cdot 16) + (0 \cdot 8) + (1 \cdot 4) + (0 \cdot 2) + (1 \cdot 1)
   \]
   \[
   = 512 + 256 + 128 + 16 + 4 + 1
   \]

3. Sum the values:
   \[
   512 + 256 + 128 + 16 + 4 + 1 = 917
   \]

So, **1110010101** in binary is equal to **917** in the Hindu-Arabic numeral system.
