1. evaluate exactly square root 100- square root64 = 10- 8 = 2 is this correct?

2. evaluate the expression |-5 +3|= 2 is this correct?
3. evaluate the expression. (-6)^2 -(16/2)= (-6)^2= 36 is this correct? thank you

The first two are correct.

For #3, you have omitted the second term,
(-6)^2 -(16/2)
= (-6)^2 - ?
= 36 - ?
= ?

1. To evaluate √100 - √64, we need to find the square roots of both numbers first.

√100 = 10, and √64 = 8.

Then, we subtract 8 from 10: 10 - 8 = 2.

So, your answer of 2 is indeed correct.

2. To evaluate the absolute value expression |-5 + 3|, we need to subtract the two numbers inside the absolute value bars first.

-5 + 3 = -2.

Since the absolute value of -2 is 2, your answer is correct.

3. To evaluate (-6)^2 - (16/2), we need to simplify both parts separately.

First, let's focus on the term (-6)^2, which means we square -6.

(-6)^2 = (-6) × (-6) = 36.

Then, we simplify the second term, which is (16/2).

16/2 = 8.

Finally, we subtract 8 from 36: 36 - 8 = 28.

Therefore, your answer of 28 is correct.
