Answer 2

Answer:

The answers are solved below.

Step-by-step explanation:

we have to solve the given expressions

Part A: The expression (-7)(-7)(-7)

$(-7)(-7)(-7)=(-1)^37^3$

Option 3 is correct

Part B: $2(5 - 3)^2 + 6^2$

First step to solve the above expression is to simplify (5-3) by BODMAS rule then to square the simplification.

Option 3 is correct.

Part C: To choose the expression  "five to the third power"

"five to the third power" is

$5^3=5.5.5=125$

All 3 represents the expression  "five to the third power"

Option 1,3,4 are correct.

Part D: The expression -8 · -8 · -8 · -8

The above expression can be written as

$(-8)^4$

Option 2 is correct

Part E: $\text{The value of } -6^2$

$-6^2=-(6\times 6)=-36$

Option 1 is correct

Part F: $\text{The value of } |5| - 4(3^2 - 2)$

$|5| - 4(3^2 - 2)=5-4(9-2)=5-4(7)=5-28=-23$

Option 4 is correct.

Part G: Evaluate $\frac{8}{ -2}\times 4^2 + 9$

$\frac{8}{ -2}\times 4^2 + 9=-4\times 16+9=-64+9=-55{$

Option 2 is correct.

Part H:  Simplify $-5^2 + 8|-1| + (-3)$

$-5^2 + 8|-1| + (-3)=-25+8-3=-17-3=-20$

Option 3 is correct.
