DESCRIBE how a power with a zero exponent (a^0) and a power with a negative exponent (a^−n) can be simplified.

is OR

= 1, where a ≠ 0

Step-by-step explanation:

To simplify the exponents, you must put it in positive value

Example:

The simplest form of is to change the exponent from negative value to positive value.

You can do that by reciprocal the number, You can write it , because 1 to any power equal 1

That means if you want to simplify , reciprocal a and change the sign of the power from -n to n

The simplest form of is OR

For any number, a (a ≠ 0), 1 × a = a, so, the reason that any number to the zero power is 1 because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, (1)

Example:

The value of = 1, because it is the product of no numbers, so it is equal to the multiplicative identity (1)

That means = 1, where a ≠ 0

Very important note:

is undefined value

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8

0.69 yards

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
