Let's evaluate each equation one by one and provide the necessary justifications.
Question 1:
Is the equation \((8 - \sqrt{4}) - 24 \times (8 - \sqrt{16}) = 8 - 48\) true or false?
-
Calculate \( \sqrt{4} \) and \( \sqrt{16} \):
- \( \sqrt{4} = 2 \)
- \( \sqrt{16} = 4 \)
-
Substitute these values: \[ (8 - 2) - 24 \times (8 - 4) = 8 - 48 \] \[ 6 - 24 \times 4 = 8 - 48 \] \[ 6 - 96 = -40 \] And on the right side: \[ 8 - 48 = -40 \]
So, the equation \( (8 - \sqrt{4}) - 24 \times (8 - \sqrt{16}) = 8 - 48 \) is True.
Question 2:
Select the response that provides the appropriate justification for the problem above.
The correct justification for the first question is:
- Because the equation can be simplified further.
Question 3:
Is the equation \( (7^{-4} \cdot 7^3)^{49} = 7 \) true or false?
-
Combine the exponents using the Product Property: \[ 7^{-4 + 3} = 7^{-1} \]
-
Now raise this to \( 49 \): \[ (7^{-1})^{49} = 7^{-49} \]
Thus, \( 7^{-49} \) does not equal \( 7 \). Therefore, the equation \( (7^{-4} \cdot 7^3)^{49} = 7 \) is False.
Question 4:
Select the response that provides the appropriate justification for the problem above.
The correct justification for the third question is:
- Because when applying the Quotient Property, the final exponent is NOT 1.
Summary:
- True
- Because the equation can be simplified further.
- False
- Because when applying the Quotient Property, the final exponent is NOT 1.
