90 to the Power of 9 = 90 ⁹ = 3.87420489E+17

Welcome to our exponent calculator! We're exploring the concept of "90 to the power of 9". Let's break down what this means and how to calculate it.

What are Exponents?

An exponent is a mathematical operation where we multiply a number (called the base) by itself a certain number of times (indicated by the power or exponent). In our case, 90 is the base, and 9 is the exponent.

Calculation

To calculate 90 to the power of 9, we multiply 90 by itself 9 times. Here's the step-by-step process:

Step	Calculation	Result
1	90	90
2	90 × 90	8100
3	90 × 90 × 90	729000
4	90 × 90 × 90 × 90	65610000
5	90 × 90 × 90 × 90 × 90	5904900000
6	90 × 90 × 90 × 90 × 90 × 90	531441000000
7	90 × 90 × 90 × 90 × 90 × 90 × 90	47829690000000
8	90 × 90 × 90 × 90 × 90 × 90 × 90 × 90	4.3046721E+15
9	90 × 90 × 90 × 90 × 90 × 90 × 90 × 90 × 90	3.87420489E+17

Solution: 90 to the power of 9 is equal to 3.87420489E+17.

How to write 90 to the power of 9 ?

Step 1: Understand the Concept

"90 to the power of 9" means we're multiplying 90 by itself 9 times. Let's break this down:

90 to the power of 9 = 90 × 90 × 90 × 90 × 90 × 90 × 90 × 90 × 90

Step 2: Learn the Notation

In mathematics, we have a special way to write this more concisely. We use superscript notation:

90⁹

Here, 90 is called the "base", and 9 is called the "exponent" or "power".

Step 3: Understand Alternative Notations

Sometimes, especially when typing or in programming, you might see it written as:

90⁹

This means the same thing as 90⁹.

Step 4: Calculate the Result

If we actually compute this:

90⁹ = 90 × 90 × 90 × 90 × 90 × 90 × 90 × 90 × 90 = 3.87420489E+17

Note: Remember, the exponent (9 in this case) tells us how many times to multiply the base (90) by itself.

Square Root

The square root is the inverse operation of squaring a number. For our example:

v4.3046721E+15 ≈ 65,610,000.0000

This is approximate because 90^9 isn't a perfect square.

Logarithm

Logarithms are the inverse of exponential functions. The logarithm of 4.3046721E+15 with base 90 should equal 9:

log₉₀(4.3046721E+15) = 9

Exponent Properties

1. Multiplying exponents with the same base: 90^a * 90^b = 90^(a+b)

Example: 90² * 90³ = 90⁵ = 5904900000

2. Dividing exponents with the same base: 90^a / 90^b = 90^(a-b)

Example: 90⁵ / 90² = 90³ = 729000

90 to the Power of 9 = 90 9 = 3.87420489E+17
