Solve the expression 15⋅8^0/5 +4(7^0−6) .
To solve this expression, we follow the order of operations (PEMDAS/BODMAS).
First, we simplify within parentheses:
7^0 = 1 (Any number raised to the power of 0 equals 1)
So, the expression becomes:
15⋅8^0/5 + 4(1−6)
Next, we simplify the exponents:
8^0 = 1
So, the expression becomes:
15⋅1/5 + 4(1−6)
Then, we perform the subtraction within the parentheses:
1 - 6 = -5
So, the expression becomes:
15⋅1/5 + 4(-5)
Next, we perform the multiplication and division from left to right:
15⋅1 = 15
So, the expression becomes:
15/5 + 4(-5)
Next, we perform the division:
15/5 = 3
So, the expression becomes:
3 + 4(-5)
Next, we perform the multiplication:
4(-5) = -20
So, the expression becomes:
3 - 20
Finally, we perform the subtraction:
3 - 20 = -17
Therefore, the solution to the expression 15⋅8^0/5 + 4(7^0−6) is -17.
