Answer:

Step-by-step explanation:
Use the Pythagorean theorem a^2 + b^2 = c^2
In this case you are given a and c, so set the equation up like
2^2 + b^2 = 8^2
b^2 = 8^2 - 2^2
b =
b =
Answer:

Answer:
![\sqrt[3]{0.000004913}=0.017](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B0.000004913%7D%3D0.017)
Step-by-step explanation:
<u>Cubic Root
</u>
The cubic root of a number N is M, if

It's usually tedious to manually compute cubic roots, but if we use some basic algebra concepts, the job is easily done.
Let's compute
![M=\sqrt[3]{0.000004913}](https://tex.z-dn.net/?f=M%3D%5Csqrt%5B3%5D%7B0.000004913%7D)
The argument can be expressed in scientific notation as

The power of 10 has an exact cubic root since the exponent is a multiple of 3. To find the cubic root of the mantissa, we note it's the triple product of 17, i.e.

Thus our number is
![M=\sqrt[3]{17^3\ 10^{-9}}=17\ 10^{-3}=0.017](https://tex.z-dn.net/?f=M%3D%5Csqrt%5B3%5D%7B17%5E3%5C%2010%5E%7B-9%7D%7D%3D17%5C%2010%5E%7B-3%7D%3D0.017)
We have then
![\boxed{\sqrt[3]{0.000004913}=0.017}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csqrt%5B3%5D%7B0.000004913%7D%3D0.017%7D)
