What is in scientific notation?

For this case we have the following multiplication:

We can rewrite the expression in the following way:

By definition, we have to:

In the multiplication, if we have the same base, the exponents are added.

Therefore, by rewriting the expression we have:

The simplified expression in scientific notation is given by:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
