Solve the expression (15*8^(0))/(5)+4(7^(0)-6). (1 point)
(15*8^(0))/(5)+4(7^(0)-6)=
Recall that any number raised to the power of 0 equals 1. Therefore, we have:
(15 * 1) / 5 + 4(1 - 6)
= 15 / 5 + 4(-5)
= 3 + (-20)
= -17
To solve the expression (15*8^(0))/(5)+4(7^(0)-6), we'll follow the order of operations (also known as PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):
Step 1: Simplify the exponent expressions:
8^(0) = 1
7^(0) = 1
Step 2: Simplify the multiplication and division:
(15 * 1) / 5 = 15 / 5 = 3
4 * (1 - 6) = 4 * (-5) = -20
Step 3: Add the results together:
3 + (-20) = -17
Therefore, (15*8^(0))/(5)+4(7^(0)-6) = -17.
To solve this expression, we need to follow the order of operations, which is commonly referred to as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
Step 1: Evaluate Exponents
In the expression, we have 8^0, which represents any number raised to the power of 0, which is always equal to 1. Therefore, 8^0 is equal to 1.
Step 2: Simplify Parentheses or Grouping Symbols
We have (15*8^(0))/(5) and 4(7^(0)-6). Let's solve them one by one.
For (15*8^(0))/(5):
Since 8^0 is 1, we can rewrite the expression as (15*1)/(5). Multiplying 15 by 1 gives us 15. And then dividing 15 by 5 gives us 3.
For 4(7^(0)-6):
Again, 7^0 is 1, so we have 4(1-6). Subtracing 6 from 1 gives us -5. Then, multiplying -5 by 4 gives us -20.
Step 3: Solve Multiplication and Division, from left to right
We have 3 + (-20). Adding 3 and -20 gives us -17.
Therefore, the solution to the expression (15*8^(0))/(5)+4(7^(0)-6) is -17.
