What is the value of 6.9 - 2^0?
A. 5.8
B. 7.9
C. 4.9
D. 6.9
The value of 6.9 - 2^0 is equal to 6.9 - 1, since any number raised to the power of 0 is equal to 1. Therefore, the value is 6.9 - 1 = 5.9.
None of the answer choices provided match 5.9.
To find the value of 6.9 - 2^0, we need to start by evaluating 2^0. Any number raised to the power of 0 is equal to 1. So, 2^0 = 1.
Now, we can substitute this value back into the original expression: 6.9 - 1 = 5.9.
Therefore, the answer is A. 5.9.
To solve this problem, we need to follow the order of operations.
First, we determine the value of 2^0. Any number raised to the power of 0 is always 1.
So, 2^0 = 1.
Then, we subtract 1 from 6.9.
6.9 - 1 = 5.9.
Therefore, the answer is 5.9.
Option A (5.8) is incorrect because 5.9 is not rounded down to 5.8.
Option B (7.9) is incorrect because 5.9 is not rounded up to 7.9.
Option C (4.9) is incorrect because the correct answer is 5.9.
Option D (6.9) is incorrect because 5.9 is not equal to 6.9.
So, the correct answer is not listed in the given options.
