hi

Step-by-step explanation:

Every number has power. It doesn't matter whether you are dealing with natural numbers or any other type of number, it will always have power. Power is an abbreviated form of writing a multiplication formed by several equal factors.

{ 5 }^{ 4 } = 5 \times 5 \times 5 \times 5

At this point, you might be wondering how come every number has power? To understand this, let's pick a number. For example, imagine the number 5. Can we write 5 like this "{ 5 }^{ 1 }"? Of course yes! Because power is basically multiplication, since we are dealing with 5 that means 5 is multiplied once. Power can be in negative as well as in a fraction or decimal form but one thing is for sure and that is every number has power. A number without power is unity. It doesn't matter whether it is ten million or a hundred billion, if their powers are zero, they will become unity. When you are dealing with powers in mathematics, you will come across two things and they are base and exponent.
