Evaluate the expression when x = -1 and y = 4. 9x^-5y^-2y
a) 9/64
b) 9/16
c) -9/64
d) -9/16

The correct option is D) -9/16

Therefore the final expression when X is equal to -1 and Y is equal to 4 is

Step-by-step explanation:

Given:

Evaluate when x = -1 and y = 4

Solution:

When x = -1 and y = 4 we hane

Identity we have

As we know  minus sign multiplied by odd number of times the number is multiplied and the assign remain same that is minus. Therefore,

Now using the above identity we get

Therefore the final expression when X is equal to -1 and Y is equal to 4 is

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
