Answer:

a - b

Step-by-step explanation:

Assuming you mean:  (a^\frac12-b^\frac12)(a^\frac12+b^\frac12)

Apply Difference of Two Squares formula (a-b)(a+b)=a^2-b^2:

\implies (a^\frac12-b^\frac12)(a^\frac12+b^\frac12)=(a^\frac12)^2-(b^\frac12)^2

Apply the exponent rule (a^b)^c=a^{bc} :

\implies (a^\frac12)^2-(b^\frac12)^2=a^1-b^1=a-b

18. Find the radius of a cylinder with a volume of 470.48 feet3 and height of 6.5 feet.
Lynna [10]
V = pi * r^2 * h
V = 470.48
h = 6.5
(pi) = 3.14
now sub

470.48 = 3.14 * r^2 * 6.5....now divide both sides by 6.5(pi)
470.48 / 6.5(3.14) = r^2 
470.48 / 20.41 = r^2
23.05 = r^2.....take sqrt of both sides, eliminating ^2
sqrt 23.05 = r
4.8 = r <==== ur radius is 4.8 ft

Write the expanded expression in expanded form using the definition of an exponent.<br> 2wz^2?
hram777 [196]

The expanded form of the given expression is 2 × w × z × z

<h3>Writing an expression </h3>

From the question, we are to determine the expanded form of the given expression

The given expression is

2wz²

To write an expression in an expanded form, we will write the expression as a repeated multiplication in the <u>simplest</u> way possible.

To do this, we will first expand the index in the given expression.

The index in the given expression is z²

Thus, we get

z² = z × z

Now, we will include the remaining individual terms in the expression and write them as product.

That is,

2wz² = 2 × w × z × z

Hence, the expanded form of the given expression is 2 × w × z × z
