Answer:
Step-by-step explanation:
You need to find the equivalent of 54 by solving and finding the root of it.
<u>GIVEN:</u><u>
</u>
2*3³
3³=27
<h2 />
2*27=54
<u>Change to square root.</u>
![\sf{\sqrt{2*3^3}}](https://tex.z-dn.net/?f=%5Csf%7B%5Csqrt%7B2%2A3%5E3%7D%7D)
Use the exponent rule.
EXPONENT RULE:
![\Longrightarrow: \sf{\:A^{B+C}=A^B\cdot \:A^C}}](https://tex.z-dn.net/?f=%5CLongrightarrow%3A%20%5Csf%7B%5C%3AA%5E%7BB%2BC%7D%3DA%5EB%5Ccdot%20%5C%3AA%5EC%7D%7D)
![\Longrightarrow: \sf{\sqrt{2\cdot \:3^2\cdot \:3}}](https://tex.z-dn.net/?f=%5CLongrightarrow%3A%20%5Csf%7B%5Csqrt%7B2%5Ccdot%20%5C%3A3%5E2%5Ccdot%20%5C%3A3%7D%7D)
![\sf{\sqrt{2\cdot \:3^2\cdot \:3}=\sqrt{3^2}\sqrt{2\cdot \:3}}](https://tex.z-dn.net/?f=%5Csf%7B%5Csqrt%7B2%5Ccdot%20%5C%3A3%5E2%5Ccdot%20%5C%3A3%7D%3D%5Csqrt%7B3%5E2%7D%5Csqrt%7B2%5Ccdot%20%5C%3A3%7D%7D)
![\Longrightarrow: \sf{\sqrt{3^2}=3}](https://tex.z-dn.net/?f=%5CLongrightarrow%3A%20%5Csf%7B%5Csqrt%7B3%5E2%7D%3D3%7D)
![\sf{3\sqrt{2*\:3}}](https://tex.z-dn.net/?f=%5Csf%7B3%5Csqrt%7B2%2A%5C%3A3%7D%7D)
<u>Then, you multiply the numbers from left to right.</u>
2*3=6
<u>SOLUTIONS:</u>
![\Longrightarrow: \boxed{\sf{3\sqrt{6}}}](https://tex.z-dn.net/?f=%5CLongrightarrow%3A%20%5Cboxed%7B%5Csf%7B3%5Csqrt%7B6%7D%7D%7D)
- <u>Therefore, the equivalent to square root of 54 is "3√6", which is the correct answer.</u>
<u></u>
I hope this helps. Let me know if you have any questions.
Answer:
52$
Step-by-step explanation:
13 (75% off) so 13 is 1/4 the price.
13x4 = 52
Answer:
C. 46.2
Step-by-step explanation:
![f(x) = 3x](https://tex.z-dn.net/?f=f%28x%29%20%3D%203x)
so
![f(15.4) = 15.4 \times 3 = 46.2](https://tex.z-dn.net/?f=f%2815.4%29%20%3D%2015.4%20%5Ctimes%203%20%3D%2046.2)
