1. F(x)=3.50+.25(22) which equals 9.

2. In order to find the greatest amount of words you need to have a variable representing the amount of words, its easiest to use X. In the equation I used above I put 22 in place of the X so since your trying to find the X the equation you’ll use is 15=3.50+.25(X) and solve to find X=46 words is the max he can use which will equal exactly 15 dollars. You put 15 on the other side of the equation because you need it to be equal to 15 dollars in the end.

Answer:

a = 15

b = 7

c = 4

Step-by-step explanation:

Given in the question an expression $\sqrt[4]{15}^{7}$

This expression can be written as $15^{\frac{7}{4} }$

As we know that roots are most often written using a radical sign, like this, $\sqrt[n]{x}$ But there is another way to represent the taking of a root.

You can use rational exponents instead of a radical. A rational exponent is an exponent that is a fraction. For example, $\sqrt[n]{x}$ can be written as $x^{\frac{1}{n} }$

Secondly two powers having same base can be multiply

$x^{n}(^{m})=x^{nm}$
