Answer:
She Flipped the symbol
Step-by-step explanation:
Please don't cry. I will explain it to you. Just please don't cry.
She multiplied correctly. But in her end result, she flipped the symbol.
You only flip symbols when multiplying or dividing by a negative number.
I hope this helps! Please don't cry :)
Answer:
x = (3, 4)
(I'm assuming the missing sign in the picture is a negative (-))
1 inch=1515 miles
X inches= 385 miles
so 1515 is 3.935 times bigger than 385 miles.
meaning that 1 inch is also 3.935 times bigger than X inches.
to find X we just divide 1 by 3.935
which is: 0.254 inches
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)
.
