Step-by-step explanation:
(5^3x*25-4)/25=625
125^3x-4=625*25
5^x-4=15625
5^x=15625-4
5^x=15621 I can't solved by me if there is only 15625 then the answer will be 6 because 5^6=15625 but there is -4 too
Answer: 1/5
Step-by-step explanation:
(1--1)/(4--6) = 2/10 = 1/5
The problem deals with a division and the rest of it, that is dividing the total amount of pencils into 9 classrooms and the rest, lets express it as fraction:
935/9 = 103 + 8/9
that is, if we multiply 103*9 we get 927 and are 8 pencils left over, therefore, 8 pencils are donated to the library and each classroom gets 103 pencils, in total 935 pencils are donated.
