Solve the expression
15⋅8^0/5 + 4 (7^0−6) = ?
15⋅8^0/5 + 4 (7^0−6) = 15⋅1/5 + 4 (1−6)
= 15/5 + 4(-5)
= 3 + (-20)
= -17
To solve the expression, we follow the order of operations (PEMDAS).
Step 1: Evaluate the exponent.
8^0 = 1
7^0 = 1
Step 2: Calculate the expression within parentheses.
7^0 - 6 = 1 - 6 = -5
Step 3: Perform the multiplication and division from left to right.
15 * 8^0 / 5 = 15 * 1 / 5 = 15 / 5 = 3
Step 4: Perform the addition and subtraction from left to right.
3 + 4 * (-5) = 3 + (-20) = -17
Therefore, the value of the expression is -17.
To solve the expression 15⋅8^0/5 + 4 (7^0−6), we can follow the order of operations (also known as PEMDAS).
Step 1: Simplify within parentheses.
In the expression 7^0−6, the exponent 0 indicates any number to the power of 0 is equal to 1. Therefore, we have 1−6, which equals -5.
Step 2: Calculate the multiplication.
Next, we can evaluate the multiplication term by multiplying 15 and 8^0. Since any number to the power of 0 is equal to 1, 8^0 is also equal to 1. Therefore, we have 15⋅1/5.
Step 3: Evaluate the division.
Now, we need to divide the product from step 2 (15⋅1) by 5. This gives us 15/5, which equals 3.
Step 4: Multiply the remaining terms.
Lastly, we multiply the result from step 3 (3) with the remaining term 4 times -5. This gives us 3⋅(-5) = -15.
Therefore, the expression 15⋅8^0/5 + 4 (7^0−6) is equal to -15.
