# Who started the hospital?

## Who started the hospital?

The earliest general hospital was built in 805 AD in Baghdad by Harun Al-Rashid. By the tenth century, Baghdad had five more hospitals, while Damascus had six hospitals by the 15th century and Córdoba alone had 50 major hospitals, many exclusively for the military.

**Is 0 in the empty set?**

One of the most important sets in mathematics is the empty set, 0. This set contains no elements. When one defines a set via some characteristic property, it may be the case that there exist no elements with this property.

**Is Infinity equal to zero?**

Zero is not equal to infinity. Zero is a number but not infinity. 0 is both a number and the numerical digit used to represent that number. Infinity is a number greater than any assignable quantity or countable number (symbol ∞).

### What is infinity to the 0 power?

one

**What is the value of 0 * infinity?**

This also points to the fact that infinity is not a number , rather a concept and hence multiplication does not hold any meaning in this case, as proved above. Remember that although infinity is a concept, a number can tend to infinity. So 0*inf is undefined.

**What is Ln infinity?**

1 Answer. Amory W. The answer is ∞ . The natural log function is strictly increasing, therefore it is always growing albeit slowly.

#### What is Arctan of infinity?

The arctangent is the inverse tangent function. The limit of arctangent of x when x is approaching infinity is equal to pi/2 radians or 90 degrees: The limit of arctangent of x when x is approaching minus infinity is equal to -pi/2 radians or -90 degrees: Arctan ►

**What Infinity subtracts infinity?**

It is impossible for infinity subtracted from infinity to be equal to one and zero. Using this type of math, we can get infinity minus infinity to equal any real number. Therefore, infinity subtracted from infinity is undefined.

**Why is 1 to the power of infinity undefined?**

Since the asymptote is a line that a curve gets infinitely close to, but never reaches, the function can never reach a real value at x=infinity. Hence, we say it is undefined.

## What is infinity divided 0?

undefined

**What is 1 to the infinity power?**

1 raised to power infinity is always 1. If one considers LHL, x will tend to 1 (from left side of 1 on the number line) but will always be less than 1, and raising infinity on something which is less than one will approach to ZERO.
