Prove that 25^11−5^19 is divisible by 31.
SCORPION-xisa [38]

Answer:

Divisible by 3 is the answer

Step-by-step explanation:

First get everything to have the same base of 5

25^11 - 5^19

(5^2)^11 - 5^19

5^(2*11) - 5^19

5^22 - 5^19

Now factor out the GCF 5^19 to get

5^22 - 5^19

5^(19+3) - 5^(19+0)

5^19*5^3 - 5^19*5^0

5^19(5^3 - 5^0)

5^19(125 - 1)

5^19*(124)

At this point, we factor the 124 into 31*4 to end up with this full factorization: 5^19*31*4

Therefore, 25^11 - 5^19 is equivalent to 5^19*31*4

Since 31 is a factor of the original expression, this means the original expression is divisible by 31.

A bracelet costs $39.59 including tax.It is marked down 25 percent.What is the final price of the bracelet after it is marked do
lara31 [8.8K]
If it is marked down 25% and 25% equals 25/100 then you simply take 39.59 x 25/100

39.59 x 25/100 = 9.90

and then you subtract that from the original price 

39.59 - 9.90 = $29.69

after it is marked down, the price is $29.69
