Answer:
Step-by-step explanation:
Step 1: First apply radical rule in the given expression.
![\sqrt[n]{a}=a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
Here, ![\sqrt[3]{7}=7^{\frac{1}{3}}, \sqrt[5]{7}=7^{\frac{1}{5}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B7%7D%3D7%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%2C%20%5Csqrt%5B5%5D%7B7%7D%3D7%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D)
The expression becomes ![\frac{\sqrt[3]{7}}{\sqrt[5]{7}}=\frac{7^{\frac{1}{3}}}{7^{\frac{1}{5}}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B7%7D%7D%7B%5Csqrt%5B5%5D%7B7%7D%7D%3D%5Cfrac%7B7%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%7D%7B7%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D%7D)
Step 2: Now, apply exponent rule in the above expression
So, the expression becomes, 
.
Step 3: Take cross multiply the denominator and numerator of the fraction in the power of 7.
The answer is .
Hence the simplified form of ![\frac{\sqrt[3]{7}}{\sqrt[5]{7}}=7^{\frac{2}{5}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B7%7D%7D%7B%5Csqrt%5B5%5D%7B7%7D%7D%3D7%5E%7B%5Cfrac%7B2%7D%7B5%7D%7D)
.
Answer:37.5
Step-by-step explanation:
5*750/100 =37.5
Answer:
5.38 ounces
Step-by-step explanation:
Given that :
Alice height = 1 mile
Distance of earth to moon = 239000 miles
Number of base 10 cakes required so they Alice's head just touches the moon ;
Using the relation :
Distance = height per ounce * 10^number of ounces
Height per ounce = 1 mile ;
Let number of ounces = n
Hence,
239000 = 1 * 10^n
239000 = 10^n
Take log of both sides
Log(239000) = n
5.3783979 = n
5.3784 = n
Hence, Alice should take 5.38 ounces of base 10 cakes
Hello from MrBillDoesMath!
Answer:
-31m + 15
Discussion:
-7m-3(8m-5) =
-7m - 3*8m + (-3)(-5) =
