Answer:

A = (a+b)/2

G = sqrt(ab)

Step-by-step explanation:

To find the arithmetic mean, we add the numbers together, then divide by how many numbers

A = (a+b)/2

To find the geometric mean, we multiply the numbers and take the nth root

G = (ab) ^ 1/2

G = sqrt(ab)

Vinil7 [7]

10% of 360.26 is 36.026 but that answer wouldn’t be it since cents are only in the tenths and hundredths places after the decimal, so you’d probably have to round it up to 36.03

Choose the appropriate pattern and use it to find the product: (p4−q4)(p4+q4).

sp2606 [1]

The expression can be solved by expanding the bracket and multiplying out the terms

$(p^4-q^4)(p^4+q^4)$ $\begin{gathered} =p^4(p^4+q^4)-q^4(p^4+q^4) \\ =p^8+p^4q^4-p^4q^4-q^8 \\ =p^8-q^8 \end{gathered}$

Therefore, the expression can be simplified as;

$p^8-q^8$

Alternatively, using the theorem of difference of two squares, which is

$a^2-b^2=(a-b)(a+b)$

Hence,

$p^8-q^8=(p^4)^2-(q^4)^2$
