What is the value of any number raised to the 0th power?

• 0

• The number itself

• Undefined

• 1

What is the result of 'x' to the 1st power?

• 0

• x squared

• 1

• x

Why is 'x' to the 0th power equal to 1?

• Because 0 times any number is 0

• Because 1 is the multiplicative identity

• Because it is defined that way in mathematics

• Because 0 added to any number is the number itself

What does the identity property of multiplication imply about exponents?

• Multiplying a number by 1 leaves it unchanged

• Multiplying a number by -1 negates it

• Multiplying a number by itself squares it

• Multiplying a number by 0 makes it 0

How do you solve the equation 'the square root of x = 3'?

• Square both sides

• Take the square root of 3

• Subtract 3 from x

• Divide x by 3

How do you isolate 'x' in the equation 'the square root of x = 3'?

• Subtract 3 from both sides

• Divide both sides by 3

• Add 3 to both sides

• Square both sides

What does squaring the square root of 'x' accomplish?

• It returns the original value of 'x'

• It squares the value of 'x'

• It makes 'x' negative

• It doubles the value of 'x'
