In scientific notation, this can be written as 7.29 x 10^2. The 10^2 indicates that we move the decimal point two places to the right to get the final number. This notation is commonly used in scientific and mathematical calculations to represent extremely large or small values.

### Real-Life Examples of 9 to the Power of 3

While the concept of 9 to the power of 3 may seem abstract, it has real-life applications. One example is in computer storage. A byte is a unit of digital information, and a terabyte (TB) is equivalent to 1 trillion bytes. If we consider a hard drive with a capacity of 9 terabytes, we can calculate the total number of bytes it can store by raising 9 to the power of 3. This gives us 729 terabytes or 729 trillion bytes, which is an enormous amount of storage capacity.

Another real-life example is in the field of physics. When studying the behavior of matter, scientists use mathematical models that involve exponents. For instance, when calculating the force exerted by an object due to its weight, the equation involves raising the mass of the object to the power of 3.
