If (-3) to the exponent of -5 = 1/x , what is the value of x? -243 -1/243 1/243 243

Use the rule that x^(-k) = 1/(x^k) to get

(-3)^(-5) = 1/(  (-3)^5 ) = 1/( -243 )

Comparing 1/( -243 ) with the form 1/x, we see that x = -243

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.

yes
