274.6 = 2.746 x 10n n =

Given that,

An equation : 274.6 = 2.746 x 10n

To find,

The value of n.

Solution,

We have, 274.6 = 2.746 x 10n

Dividing both sides by 2.746 .

Now dividing both sides by 10.

n = 100/10

n = 10

So, the value of n is 10.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

c) yes, because of asa or aas
