If \frac{3+\sqrt{8} }{3-\sqrt{8} } +\frac{3-\sqrt{8} }{3+\sqrt{8} }=a+b\sqrt{2}, the value of a and b is given as a = 34 and b = 0

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables or numbers.

\frac{3+\sqrt{8} }{3-\sqrt{8} } +\frac{3-\sqrt{8} }{3+\sqrt{8} }\\ \\\frac{9+6\sqrt{8}+8+9-6\sqrt{8}+8  }{(3-\sqrt{8} )(3+\sqrt{8} )} \\\\\frac{34}{9-8} =34+0\sqrt{2}

If \frac{3+\sqrt{8} }{3-\sqrt{8} } +\frac{3-\sqrt{8} }{3+\sqrt{8} }=a+b\sqrt{2}, the value of a and b is given as a = 34 and b = 0

The undefined terms in geometry are points, lines and planes.

  • A point's location on the coordinate plane is indicated by an ordered pair, (x, y). TRUE. In R², the ordered pairs (x,y) is used to defined the location of a point.
  • The second statement is false because a point has no dimension.
  • The third statement is also false because a line has only one dimension which is length.
  • The fourth statement is not true because distance between two points must have a beginning and an end.
  • A plane consists of an infinite set of points. TRUE .The plane is a home of infinitely many points.

How do changes in voltage or resistance affect current in an electric current ?
mihalych1998 [28]

Answer:

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.
