Which answer choice is equivalent to the expression below?

3x2y4/2xy
the 2 and 4 in the first part of problem(not the 2 from 2xy) are exponents.

a.3xy3/2 ( the second 3 is exponent )
b.3x3y5/2 (the second 3 is exponent, and the 5)
c.3/2xy3 ( the 3 in 2xy3 is exponent)
d.3xy2/2 ( the 2 in 3xy2 is an exponent.)

The correct option is A.

Step-by-step explanation:

The given expression is

It can be written as

According to quotient property of exponent:

Using quotient property of exponent, we get

The expression is equivalent to the given expression.

Therefore the correct option is A.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
