Exponents in real life exponents are a simplified way to show repeated multiplication. It consists of a base, which is the number that you are multiplying, and an exponent or power, which is how many times you are multiplying the base. There are many ways in which you can use exponents in real life. For example, computers, engineering, bacterial growth, or building houses. They are often used while talking about very big, or very small things. The example that I am going to use is bacterial growth. let's say that we have one million bacteria. These bacteria double their quantity in an hour. we start with one million, then we go on to two million bacteria, then four, eight, and so on and so forth. The math equation that we would then have would be The mathematical equation for after 24 hours of doubling quantity every hour, would be 1xE^24. This means 1x10 to the power of 24. The final answer would be 1 000 000 000 000 000 000 000 000. This number is called septillian. The impact that this has on science is being able to know how fast it takes a type of bacteria to grow into large numbers. if exponents weren't used for this, it would make it alot harder to make a more accurate prediction on how much bacteria there would be in a period of time.
