Understanding Zero Exponents

Arthur Morris explains the concept of exponents of zero, demonstrating that any number raised to the zero power equals one. Through various examples, he illustrates how to simplify expressions with exponents of zero, including handling negative numbers and using the quotient rule. The video aims to clarify this mathematical principle with practical examples.

What is the result of any number raised to the power of zero?

• Zero

• One

• Infinity

• The number itself

In the expression 3 * (-2/5)^0, what does (-2/5)^0 simplify to?

• -2/5

• 0

• 1

• 3

Why does 5^0 equal 1?

• Because 5 is a prime number

• Due to the quotient rule and division by itself

• Because zero is a neutral element

• It's a mathematical anomaly

What is the result of -9^0?

• 0

• -1

• 9

• 1

In the expression (2^7)^0 * -3, what does (2^7)^0 simplify to?

• 2^7

• 0

• 1

• -3
