Answer
39 bills of 1$
16 bills of 10$
Step-by-step explanation:
x-nr of $1
y-nr of $10
x*1+y*10=199
x+y=55 , x=55-y
so I use the substitution method
(55-y)*1+10y=199
55+10y-y=199
-55 -55
9y=144
y=144/9
y=16
so x=55-16
x=39
verify 16*10+39*1=160+39=199

Given: 2 *
;
Simplify this given expression:
Let us list the factors of: 81:
1, 2, 3, 9, 27 , 81 .
________________________________________
Are any of these factors "perfect cubes"?
Let's see: ∛27 = 3 ; (use calculator); since: " 3³ = 3 * 3 * 3 " .
81 = 27 * 3 ;
So: " ∛(81) " ;
= ∛(27) * ∛(3) ;
= " 3 * ∛3 " ;
________________________________________
→ The original expression:
" 2 * ∛81 " ;
________________________________________
= 2 * 3 * ∛3 ;
= (2 * 3) * ∛3 ;
= 6 ∛3 .

The answer is: " 6 ∛3 " .
