Overview of RS Aggarwal Class 8 Solutions Chapter 2 Exponents

Exponents are nothing more than the regular, repeating multiplication of the same numbers. Exponents often come in two parts: base and power, or Exp (p­­)-n. Here, n is the power or exponent, and P is the base. The computation of exponents is subject to a set of rules.

The value will remain the same as the base if b has a power of one. Any base’s power of zero transforms any value into one. By keeping the base constant and logically adding the powers, two exponents with the same base but different powers are calculated. An integer’s value is equal to 1/the exponent when its power is negative.

Exponents are intricate structures, nevertheless. These have numerous uses in a variety of disciplines, including computer science, chemistry, biology, and physics. This is important when discussing population expansion and calculating chemical kinetic energy.

Why Do We Need Exponential Numbers

You’re probably wondering why we need to write 22 when we could just write 4 in its place. Small numbers are simple to calculate, manage, and remember, but you could find it difficult to recall large amounts.

Do you know that the earth weighs 5,976,000,000,000,000,000,000,000 kg, for instance. It might be difficult for anyone to recall how many zeros there are in this. However, it is much simpler to recall when we write that the mass of the earth is approximately 5.976 x 1024 kg.

The Transformation of large numbers into exponential form

Let’s say you want to convert the number 189,000,000,000,000 to standard form. This number’s first digit on the left is “1.” There are 14 digits after that. In this case, 14 would be the exponent. Then, after the leftmost digit, we will add a decimal point and leave the non-zero digits alone. We’ll represent the number as 1.89 X 1014 after removing the zeros.

The conventional representation for the number 16783000 will be 1.6783 X 107.

If the decimal number is 0.0000028474, then 2.8474 x 10-6 will be used as its standard form. Since the decimal point has been advanced six places in this example, the exponent is shown as negative six.
