15x8^0/5 + 4 (7^0 - 6)
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
To solve this expression step-by-step, let's start by simplifying each part of the expression according to the order of operations (PEMDAS/BODMAS).
Step 1: Evaluate the exponent (8^0):
8^0 = 1 (Any number raised to the power of 0 equals 1.)
Step 2: Simplify the multiplication and subtraction inside the parentheses:
7^0 - 6 = 1 - 6
= -5
Step 3: Substitute the simplified values back into the expression:
15 * 1 / 5 + 4(-5)
Step 4: Perform the multiplication and division from left to right:
15 / 5 + 4(-5) = 3 + 4(-5)
Step 5: Perform the multiplication:
4(-5) = -20
Step 6: Add the results together:
3 + (-20) = -17
Therefore, the simplified expression is -17.
To solve this expression, let's break it down step by step:
Step 1: Evaluate any exponents.
In this expression, we have 8^0 and 7^0 as exponents. The exponent of 0 means any number raised to the power of 0 is equal to 1. So, we can rewrite the expression as:
15x1/5 + 4(1 - 6)
Step 2: Perform any multiplication or division.
Now, let's simplify the multiplication and division:
15/5 + 4(1 - 6)
The division of 15 by 5 gives us 3:
3 + 4(1 - 6)
Step 3: Simplify any addition or subtraction.
Next, let's simplify the addition/subtraction:
3 + 4(-5)
Multiplying 4 by -5 gives us -20:
3 + (-20)
Simplifying further, 3 + (-20) is equal to -17:
-17
Therefore, the value of the expression 15x8^0/5 + 4 (7^0 - 6) is -17.
