When you have fractions in the exponent, the denominator is the root and the numerator is the power on the number inside the root.

4^(1/7) = ⁷√(4)
4^(7/2) = √(4)^7
7^(1/4) = ⁴√(7)
7^(1/2) =  √(7)

Answer:

Radical form refers to a form of an algebraic expression in which we have a number or an expression underneath a radical.

Any algebraic expression involving exponents then, we can write it in radical form based on the fact that  x^{\frac{a}{n}} is equivalent to the nth root of x^a i.e,

x^{\frac{a}{n}} =\sqrt[n]{x^a}

Now, Consider the expression:

4^{\frac{1}{7}} = \sqrt[7]{4}

4^{\frac{7}{2}} = \sqrt[2]{4^7}

7^{\frac{1}{4}} = \sqrt[4]{7}

7^{\frac{1}{2}} = \sqrt[2]{7}

Which function represents g(x), a reflection of f(x) = (3)x across the y-axis?
Artyom0805 [142]

Answer: g(x)=(3)^{-x}

Step-by-step explanation:

We know that if a figure is reflected across y axis then its y coordinate remains same but the x coordinate changes its polarity.

i.e. the function f(x) will become f(-x) .

Now, the given function :f(x)=(3)^x

Then , after reflection across y axis the new function will become:

g(x)=f(-x)=(3)^{-x}

Bag of skittles containes 3 colors . red, yellow,, and green - in the ratio of 1:2:5 if there were a total of 32 pieces of candy
steposvetlana [31]
With the 3 colors - red=1, yellow=2 and green=5 - adding up to 8, that is one quarter the total of 32.  Multiply each by 4 and you'll have - 4:8:20.
