Answer:

4

Step-by-step explanation:

10y^2/ z

10(-2)^2/-5

10 ×-2 =-20

-20÷-5=4

The value of the expression is -8.

The expression when y=−2 and z=−5 in 10y²/z will be gotten by putting the values of y and z into the expression that's given. This will be:

10y²/z = 10(-2)²/-5

= 10(4)/-5

= 40/-5

= -8

In conclusion, the value of the expression is -8.
