Assuming the question reads:


5 \cdot 3^2 - 15 / 5

The order of operations is as follows:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

There are no parentheses in the equation.

There is an exponent in the equation. Solve this term first:


3^2 = 9

The equation should now read:


5 \cdot 9 - 15 / 5

There are two multiplication/division operations in the equation. Solve them individually:


5 \cdot 9 = 45


15 / 5 = 3

The equation should now read:


45 - 3

There is one subtraction operation. Solve this term for your answer:


45 - 3 = \boxed{42}
