Question

15x8^0/5 + 4 (7^0 - 6)

Answer 1

To solve this expression, we must follow the order of operations, which is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

We start with the exponent operation. Any number raised to the power of 0 equals 1, so 8^0 becomes 1.

Now the expression becomes:
15 * 1 / 5 + 4(1 - 6)

Next, we solve the parentheses:
1 - 6 = -5

Now the expression becomes:
15 * 1 / 5 + 4(-5)

Next, we perform multiplication and division from left to right:
15 * 1 = 15
15 / 5 = 3

Now the expression becomes:
3 + 4(-5)

Finally, we perform multiplication:
4 * -5 = -20

The final expression is:
3 + (-20) = 3 - 20 = -17
