Question

Which expression has a positive value?

Answer 1

Answer:

3rd expression has a positive value.

Step-by-step explanation:

(1) -4 + (-5) $[\frac{(-6)}{(-3)}]$

= -4 + (-5) × 2

= -4 -10

= -10

(2) 8 $[\frac{10}{2(-2)}]$

=$\frac{80}{(-4)}$ = -20

(3) 3 $[\frac{-64}{8}]+25$

= 3(-8) + 25

= -24 + 25

= 1 [positive value]

(4) $\frac{(-2)(-5)(-3)}{10}$

$=\frac{+10(-3)}{10}$

= -3

3rd expression has a positive value.

Answer 2

3(-64/8)+25 will give you a positive value of 1
