Question

Give the example for first law of exponents
​

Answer 1

Answer:

The exponent of a number says how many times to use the number in a multiplication.

In this example: 82 = 8 × 8 = 64

In words: 82 could be called "8 to the second power", "8 to the power 2" or simply "8 squared"

34 = 3 × 3 × 3 × 3 = 81©

v0.82

So an Exponent saves us writing out lots of multiplies!

Example: a7

a7 = a × a × a × a × a × a × a = aaaaaaa

Notice how we wrote the letters together to mean multiply? We will do that a lot here.

Example: x6 = xxxxxx
