5^5-9(200/4)-(10*90)/5-4^4(5)+156-256
= 3125-9( 200/4)-(10*90)/5-(4^4)(5)+156-256
= 3125-(9)(50)- (10*90)/5-(4^4)(5)+156-256
= 3125-450- (10*90)/5-(4^4)(5)+156-256
= 2675-(10*90)/5-(4^4)(5)+156-256
= 2675 - 900/5 - (4^4)(5)+156-256
= 2675 - 180 - (4^4)(5)+156-256
= 2495 - (4^4)(5)+156-256
= 2495 - 1280 + 156 -256
= 1215 + 156 - 256
= 1371 - 256
= 1115
I hope that's help , please if you have question(s) just let me know !

Answer:
28.25 million
Step-by-step explanation:
Population of the country:
- in 2001 - x million
- in 2006 - 30.4 million
Population of the country as percent:
- in 2001 - 100%
- in 2006 - 100% + 7.6% = 107.6%
Write a proportion:

Cross multiply:

Divide by 107.6:

Answer:
The GCF for the variable part is
k
Step-by-step explanation:
Since
18
k
,
15
k
