Answer:
x^4 - 81 = 0
(x² - 9)(x² + 9) = 0
Notice that the first of these is itself a difference of two squares:
(x - 3)(x + 3)(x² + 9) = 0
So the solutions are x = 3, x = -3, x = 3i, x = -3i
Pq= 10.5, qr=31.5, rs=10.5, sp=31.5
"<span>The volume of a cylinder with height h and radius r is given by the formula below. V = Πr 2 h Complete the equation below by writing an equation equivalent to height, h, of a cylinder.
Please, instead of "</span>V = Πr 2 h," type V = pi*r^2*h: "pi times radius squared times h"
V
This can be solved for the height of a cyl.: h = ---------
pi*r^2
Use " ^ " to denote exponentiation, please.
