What is (-m)^-3n, if m= 2 and n= -24?
a. 3
b. -3
c. 4.
d. -4

Option (a) is correct.

The value of expression when m = 2 and n = -24 is 3.

Step-by-step explanation:

Given expression

We have to evaluate the value of given expression when m = 2 and n = - 24

Consider the given expression ,

to find the value of expression at m = 2 and n = -24

Substitute in the expression the values of m and n

Using property of exponents,

We get,

Solving further, we get,

On solvine we get

Thus, the value of expression when m = 2 and n = -24 is 3.

Thus, option (a) is correct.

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
