Prove the divisibility of the following expressions:

10^6−5^7 is divisible by 59
81^7−27^9−9^13 by 45

A divisibility test is a rule to determine whether one whole number is divisible by another number.

If after dividing a number by a number we get an integer then we can say that the number is divisible by the number.

1) Here, the given expression,

Which is an integer,

⇒ is divisible by 59.

2) Here, the given expression,

Which is an integer,

⇒ is divisible by 45.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
