Find f(x)=x 4/7+9/14 can someone help me solve this as a improper fraction

Answers

the expression in the form of an improper fraction is: f(x) = (14x^(4/7) + 9) / 14. To find f(x) when f(x) = x^(4/7) + 9/14, we need to combine the terms on the right-hand side and simplify the expression.

Step 1: Combine the terms on the right-hand side:

f(x) = x^(4/7) + 9/14

Step 2: To express x^(4/7) as an improper fraction, we raise x to the power of 4/7. Remember that the denominator of a fraction represents the root (in this case, the 7th root) and the numerator represents the power (in this case, 4).

x^(4/7) = (x^4)^(1/7)

Step 3: Simplify the expression (x^4)^(1/7):

(x^4)^(1/7) = x^(4/7)

Now, the expression becomes:

f(x) = x^(4/7)+ 9/14

Step 4: To make a common denominator for adding the fractions, find the least common multiple (LCM) of 7 and 14, which is 14.

Step 5: Rewrite both fractions with a denominator of 14:

f(x) = (14/14) * x^(4/7) + (9/14)

Step 6: Combine the fractions:

f(x) = (14x^(4/7) + 9) / 14

So, the expression in the form of an improper fraction is:

f(x) = (14x^(4/7) + 9) / 14

so you multiply the top and bottom of the first fraction by two, so that both fractions have 14 on the bottom, then we can simply add across the top

An astronaut who weighs 126lb on Earth weighs only21lb on the moon. How much would a person who weights 31lb on the moon weigh on Earth?

Answers

If his weight on Earth is 126lb and only 21lb on moon, you can divide 126/21 to see what is the ratio of those weights.
126/21=6

It means that your weight on moon will be 6 times less than on Earth.

Now we have to multiply 31lb which is weight of the person on moon by 6 to get his weight on Earth 6*31=186
On moon our mass becomes 1/6 of actual mass so if you weigh 60 kg then your mass on moon will be 10 kg..
Similarly if your mass on moon is 31 lbs then your mass on earth will be 31*6=186 lbs.
