An exponent is shorthand for repeated multiplication.  for example, 
n4
=n·n·n·n.   in an exponential expression like ba, b is called the base and a is called the exponent.
expand each of the expressions below. for example, to expand
x3, you would write: x·x·x.

1. y7



2. 5(2m)3



3. (x3)2



4. 4x5y2



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

well the answer to that is xoxoxo

step-by-step explanation:

idk

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
