Question

create an equation: the temperature dropped 3° per hour. how much did the temperature drop in;
what is the value of each expression?
8(-4)
(- 3)³
(- 6)²

Explanation:

Step1: Evaluate \( 8(-4) \)

Multiply 8 and -4. The product of a positive and a negative number is negative. So, \( 8\times(-4)= -32 \).

Step2: Evaluate \( (-3)^3 \)

Cube of -3 means multiplying -3 three times: \( (-3)\times(-3)\times(-3) \). First, \( (-3)\times(-3)=9 \), then \( 9\times(-3)= -27 \).

Step3: Evaluate \( (-6)^2 \)

Square of -6 means multiplying -6 by itself: \( (-6)\times(-6) \). The product of two negative numbers is positive, so \( (-6)\times(-6)=36 \).

Answer:

• For \( 8(-4) \): \(-32\)
• For \( (-3)^3 \): \(-27\)
• For \( (-6)^2 \): \(36\)
