Question

What is the value of 3^2x+1, if 3^x=a

Guys HELPPPPP

Answer 1

Step-by-step explanation:

We use the power rule a^(x+y) = a^x * a^y:

3^(2x+1) = 3^(2x) * 3

We can re-write 3^(2x) as (3^x)^2, and we know that 3^x = a, so:

3a^2 is the final answer. There is not exact value, it's all just about re-writing.

Answer 2

$3a^2$ is a required answer.

Answer:

solution given:

$3^{2x+1}=?$

if $3^x=a$

By using power rule, we can write

$3^{2x+1}$ as

$3^{2x+1}=(3^x)^2*3^1$

$a^2*3=3a^2$
