There are no marks to conclude that the sides of the triangle are congruent, it doesn't mean they're not, it just means there is a chance that the side-side-side is out. I am not sure if the AB=C is referring to the angles A, B and C, or if it referring to line segment AB.
The missing value is 24
you can solve this by dividing 30 by 5 (6) and then multiplying that by 4
Answer:
jgfshd
Step-by-step explanation:
Remark work with the two numbers that are 10^4 first. Then add in the one that goes to 10^3
Method one
You could change these all to integers and then take it back to scientific notation.
83 000
<u>-19 000</u>
64 000
<u>- 2 500
</u> 61 500 <u /><<<<<< answer
Method two
Keep the scientific notation.
8.3 * 10^4
<u>-1.9 * 10^4</u>
6.4 * 10^4
<u>- .25*10^4</u> Note the powers of ten must be the same.
6.15*10^4 <<<<<<<< answer
<u>
</u>Either method works.
<u>
</u>You could use your calculator to get the right answer. I'm not sure all calculators retain the scientific notation. Test yours to see what it does. Enter 8.3*10y^x 4 *1 =
<u>
</u>Your calculator might have x^y or ^ to record powers. You may also have EE and one of your keys.
<u>
</u>See if your calculator returns 8.3*10^4 or if it returns 83000<u>
</u>

![\sqrt[3]{2y^3} * 7\sqrt{18y} = 21(y^{\frac{3}{2}})(2^{\frac{5}{6}})](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2y%5E3%7D%20%2A%207%5Csqrt%7B18y%7D%20%3D%2021%28y%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%29%282%5E%7B%5Cfrac%7B5%7D%7B6%7D%7D%29)
Step-by-step explanation:
The question is poorly formatted.
Given
![\sqrt[3]{2y^3} * 7\sqrt{18y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2y%5E3%7D%20%2A%207%5Csqrt%7B18y%7D)
Required
Derive an equivalent expression
Express 18 as 9 * 2
![\sqrt[3]{2y^3} * 7\sqrt{9 * 2y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2y%5E3%7D%20%2A%207%5Csqrt%7B9%20%2A%202y%7D)
Split the expression as follows:
![\sqrt[3]{2y^3} * 7\sqrt{9} * \sqrt{2y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2y%5E3%7D%20%2A%207%5Csqrt%7B9%7D%20%2A%20%5Csqrt%7B2y%7D)
Take positive square root of 9
![\sqrt[3]{2y^3} * 7*3 * \sqrt{2y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2y%5E3%7D%20%2A%207%2A3%20%2A%20%5Csqrt%7B2y%7D)
![\sqrt[3]{2y^3} * 21 * \sqrt{2y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2y%5E3%7D%20%2A%2021%20%2A%20%5Csqrt%7B2y%7D)

The cube root can be rewritten to give:
![21*\sqrt[3]{2}*\sqrt[3]{y^3} * \sqrt{2y}](https://tex.z-dn.net/?f=21%2A%5Csqrt%5B3%5D%7B2%7D%2A%5Csqrt%5B3%5D%7By%5E3%7D%20%2A%20%20%5Csqrt%7B2y%7D)
![\sqrt[3]{y^3} = y^{3*\frac{1}{3}} = y](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%5E3%7D%20%3D%20y%5E%7B3%2A%5Cfrac%7B1%7D%7B3%7D%7D%20%3D%20y)
So, we have:
![21*\sqrt[3]{2} * y * \sqrt{2y}](https://tex.z-dn.net/?f=21%2A%5Csqrt%5B3%5D%7B2%7D%20%2A%20y%20%2A%20%20%5Csqrt%7B2y%7D)
