Question

Evaluate 10x2y–2 for x = –1 and y = –2.

Answer 1

Answer:

-16

Step-by-step explanation:

10 x -1= -10

2 x -2= -4

-10-4= -14

-14-2= -16

Answer 2

After evaluating the equation 10$x^{2}$$y^{-2}$ for x = -1 and y = -2,

the answer is 5/2.

Given,

The equation :

10$x^{2}$$y^{-2}$  for x = -1 and y = -2.

We have to evaluate the given equation.

We have,

10$x^{2}$$y^{-2}$  

Putting x = -1 and y = -2.

= 10 x $(-1)^{2} (-2)^-2$

= 10 x 1 x 1 / (-2)²

= 10 / 4

= 10 / 4

= 5 / 2

Thus, the equation 10$x^{2}$$y^{-2}$ for x = -1 and y = -2 is 5/2.
