What is @@(-3)^2@@?

• 6

• 9

• 3

What does a negative exponent indicate?

• It indicates the base raised to the same negative exponent.

• It indicates the reciprocal of the base raised to the opposite positive exponent. For example, @@x^{-n} = rac{1}{x^n}@@.

• It indicates that the base is multiplied by itself a negative number of times.

• It indicates that the base is equal to zero.

What is the value of @@x^0@@ for any non-zero x?

• Any non-zero number raised to the power of zero equals one.

• Any non-zero number raised to the power of zero equals zero.

• Any non-zero number raised to the power of zero equals itself.

• Any non-zero number raised to the power of zero equals negative one.

• 49

• 14

• -49

• -14

What is the value of @@8^{-1}@@?

• @@rac{1}{8}@@

• @@8@@

• @@1@@

• @@rac{8}{1}@@

What is an exponent?

• An exponent is a number that indicates how many times to multiply the base by itself. For example, in @@2^3@@, 2 is the base and 3 is the exponent, meaning @@2 * 2 * 2@@.

• An exponent is a number that represents the square of the base only.

• An exponent is a number that indicates the addition of the base to itself.

• An exponent is a number that shows the division of the base by itself.
