Answer:
Given that:
=2^(-4/5)
This means that 2 is the base and -4/5 is the exponent.
To change it in radical form:
- firstly the denominator would be written with radical sign
- Then the negative sign with 4 will be removed by inverting the base.
- Then the fraction will be simplified according to the exponent (power)
- All the steps are performed below:
![=\sqrt[5]{2^{-4} } \\=\sqrt[5]{1/2^4}\\ =\sqrt[5]{1/16}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B5%5D%7B2%5E%7B-4%7D%20%7D%20%5C%5C%3D%5Csqrt%5B5%5D%7B1%2F2%5E4%7D%5C%5C%20%3D%5Csqrt%5B5%5D%7B1%2F16%7D)
i hope it will help you!
Answer:
B
Step-by-step explanation:
2a+45=180
subtract 45 from both sides which equals 2a=135
divide both sides by 2 which would solve for a.
Acute is a angle of some sort I believe.
