3^n + 3^{n+1} = 3^n + 3×3^n

When you have for example:   3²×3³ then you have:

(3×3)×(3×3×3) = 3×3×3×3×3 = 3⁵ which is  3²⁺³

It works with any exponents, so:

if  3²⁺³ = 3²×3³ then   3ⁿ⁺¹ = 3ⁿ×3¹ = 3ⁿ×3 = 3×3ⁿ

and so:

3ⁿ + 3ⁿ⁺¹ = 3ⁿ + 3×3ⁿ

Determine the truth value of the statement if the domain for all variables is the set of nonnegative integers.
Nadya [2.5K]

The domain for all variables of the set of nonnegative integers given is true.

<h3>How to explain the truth value?</h3>

From the information given, we are given ∃n∀m(m< n). This implies that for all m, there exists n such that m × n where m and n are non negative integers.

This statement is true because for any non negative integer, the least value is zero and the set is unbounded.

What is the value of 7x 2squared + 2x when x = 3?
mash [69]

Answer:

Given expression has the value 69

Step-by-step explanation:

Given equation is:

=7x^2 + 2x

Now we have to put x = 3

So the equation will become:

=7(3)^2 + 2(3)

By simplifying:

As 3^{2} = 9

and 2*3 = 6

So the above equation will become:

=7(9 ) + 6\\= 63 + 6\\= 69

So the value of given expression is 69.

i hope it will help you!
