Answer:
Step-by-step explanation:
<u>Simplify, rationalize the denominator</u>
- √2/(3 + √5) =
- √2(3 - √5)/(3 + √5) (3 - √5) =
- (3√2 - √10)/(3² - 5) =
- (3√2 - √10)/4
Answer:
T and F
Step-by-step explanation:
Hi! Maybe I am reading it wrong, but only 2 statements are given. The answer to these statements are true and false.
"A square root of 16 is 4."

4 squared, or 4 * 4 is equal to 16, and therefore this is true.
"The only square root of 9 is -3."
This is false. 9 has 2 square roots: 3 and -3.
3 * 3 = 9, and so does (-3) * (-3).
So we have T and F, which eliminates the second, third, and fourth choices, which means even without a last statement, A is your correct answer.
Hope I helped! :)
Anything to the power 0 equals to 1
And the negative power will divided by 1 to become a positive power
So the answer is D (-z/y^7)
First you need to find how many grams is 1 ounce. 1o z.is 28.35 g, then you need to multiply 28.35 g by 5 which is 141.75. you need to round it to the nearest hundred so it is about 142 grams.
the key here would be
1 oz. = 28.35g or 1 oz. = 28 g
Hope this helps!
