This is the symmetric property of equality, and in a more general form it can be written as: if a=b then b=a.
<span>This is not to be confused with communicative property, which says that the order doesn't matter in some operations, such as addition, and can be written as a+b=b+a</span>
Answer:
I think the answer must be A.
Step-by-step explanation:
![-(7^{-3})(7^{5} )](https://tex.z-dn.net/?f=-%287%5E%7B-3%7D%29%287%5E%7B5%7D%20%29)
=> ![-(\frac{1}{7^{3} } )(7^{5} )](https://tex.z-dn.net/?f=-%28%5Cfrac%7B1%7D%7B7%5E%7B3%7D%20%7D%20%20%29%287%5E%7B5%7D%20%29)
=> ![(\frac{-1}{7^{3} } )(7^{5} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B-1%7D%7B7%5E%7B3%7D%20%7D%20%20%29%287%5E%7B5%7D%20%29)
=> -1 × 7²
=> -7²
=> -49
Hoped this helped.
Answer:
![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
Step-by-step explanation:
![\frac{12}{16} =\frac{x}{y} \\\\\frac{12}{16} =\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B16%7D%20%3D%5Cfrac%7Bx%7D%7By%7D%20%5C%5C%5C%5C%5Cfrac%7B12%7D%7B16%7D%20%3D%5Cfrac%7B3%7D%7B4%7D)
Divide the numerator and denominator by 4
Answer:
1. x = 32°
2. x = 28°
3. x = 15°
4. x = 30°
5. x = 40°
6. x = 20°
Step-by-step explanation:
All the angles should add up to 90° as they are complementary.
![9^{3}*9*9^{5}*5^{3}*5^{4}*5\\=9^{9}*5^{8}](https://tex.z-dn.net/?f=9%5E%7B3%7D%2A9%2A9%5E%7B5%7D%2A5%5E%7B3%7D%2A5%5E%7B4%7D%2A5%5C%5C%3D9%5E%7B9%7D%2A5%5E%7B8%7D)
That is your simplified answer. This is achieved through exponent laws
, where equal bases raised to powers multiplied is equal to the base raised to the powers added.
