PART TWO MATH TEST :) Please Help! I will give brainliest and donuts <33

ra1l [238]

Hey there,

Question #1

The answer would be in the attachment below.
_____________________________________________________________

Question #2

The answer would be in the attachment below.
_____________________________________________________________

Question #3

The answer would be in the attachment below.
_____________________________________________________________

Question 4#

The last one was kind of tricky. But, as I saw this attachment, I noticed on how the rectangle was actually 3/4 on the base and for the height, it was 1/2. So by doing this,we need to find the area, and we would multiply these both. 1/2 x 3/4 = 3/8 but by looking at your options, those are not simplified so . . .your answer would be 6/16 because 3x2=6 & 8x2=16.

I really hope this can help you Amanda.

Have a great day! =)

Isn’t it just 5? Why would it say check all that apply

LenKa [72]

Answer: $25^\frac{1}{2}$

Step-by-step explanation:

25 = 5*5 or -5 * -5

yes, that is correct. However, you forgot another property of roots. Roots are simply exponential fractions.

$\sqrt[n]{x^m}=x^\frac{m}{n}$

Therefore, $\sqrt{25}$ can also be rewritten as: $25^\frac{1}{2}$ . Notice that it cannot be -25 because that would be a negative square root which will give us an imaginary number.

Any number with the power of zero is always going to equal: A. 1 B. 0 C. The number

makkiz [27]

Surprise! It turns out that the answer is 1.

Why?!!??!

Notice this pattern when working with powers of 2:
2^0 2^1 2^2 2^3 2^4
? 2 4 8 16

Every time we increase the power we multiply by 2. Or reading the pattern backwards, every time we decrease the power we divide by 2. What is 2 divided by 2? It is 1! So 2^0 = 1 to finish the pattern:
2^0 2^1 2^2 2^3 2^4
1 2 4 8 16

Try it with 3 or with 5 or with any number! You'll see that the pattern holds!
