Worksheet 1:8 Power Laws Section 1 Powers In maths we sometimes like to nd shorthand ways of writing things. One such shorthand we use is powers. It is easier to write 23 than 2 2 2. The cubed sign tells us to take the number and multiply it by itself 3 times. The 3 is called the index. Then 106 means multiply 10 by itself 6 times. This means.
This formula tells us that when multiplying powers with the same base, add the indices. This is the first index law and is known as the Index Law for Multiplication. Example 7. Solution: Note: Multiply the numerical coefficients first, and then apply the index law. Key Terms. index law for multiplication.
