Answer:
Step-by-step explanation:
log8 62 = x1
8^x1= 62
8^2 =64 >62 so <u>x1<2</u>
log7 50=x2
7^x2=50
7^2=49<50 so <u>x2>2</u>
we have, x1<2  and 2<x2
x1<2<x2
x1<x2
log8 62<log7 50

Answer:
66 notes of 5 riyal
76 notes of 10 riyal
Step-by-step explanation:
(10x + 10) +5x = 1000
15x = 990
x = 66
so there are 66 of 5 riyal notes and 66 + 10 ie 76 of 10 riyal notes
 
        
             
        
        
        
5? 5 times 5 is 10, which is less than 12
