To convert the octal number (75)8 to its decimal (base 10) equivalent.

The problem asks to convert the octal number $(75)_8$ to its decimal (base 10) equivalent.

The student correctly applied the formula for converting an octal number to decimal:
For $(d_1 d_0)_8$, the decimal equivalent is $d_1 \times 8^1 + d_0 \times 8^0$.
The student wrote:

• $7 \times 8 = 56$
• $5 \times 1 = 5$
• $56 + 5 = 61$

All steps and calculations are correct.

The final answer is 61.
