a-n = 1/an = (1/a) x .... x (1/a), this last product having n factors, each is 1/a
A power (or exponent).
Power
how can exponent can make it easier to write an expression with a repeated factor in the product
power.
The product is negative.
If you are multiplying negative numbers, an odd number of factors will have a negative product. An even number of factors will have a positive product.
The base is the repeated factor, the exponent is the number of times by which the base is mutltiplied by itself. The exponent is also known as the power, althought the product of the exponential expression can also be described as the power.
Yes. The product of an odd number (21, in this case) of negative factors will be negative; if the number of negative factors is even, the product will be positive.
negative
As a product of its prime factors in exponent form: 3^6 = 729
As a product of its prime factors: 5*233*2441 = 2843765
Exponents are just shorthand for repeated factors.2 x 2 x 2 x 3 x 3 x 3 = 21623 x 33 = 216
