A) write √3×√6 in the form of b√2 where b is the insteger

b) simplify √8×√18
​

Step-by-step explanation:

a.) the given term can be written as

=

=

=

hence the given term is

where b = 3

b.)

=

=

=

=

hence the given term is 12

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
