3^2•3^n simplifies to 3^20 what is the value of the exponent n?
Lemur [1.5K]
Given that:
3^2 \times 3^n = 3^20
Solving for n.
Divide both sides by 3²
\frac{3^2 \times 3^n}{3^2} = \frac{3^{20}}{3^2}
Simplify
3^n= 3^{20-2} \\
3^n=3^{18} \\
if \ a^{f(x)}=a^{g(x)} , \ then \ f(x)=g(x)
So, n=18

Answer: n=18

Let f(x) = x + 7 and g(x) = x − 4. Find f(x) ⋅ g(x). (1 point) x2 − 3x −28 x2 − 3x − 11 x2 + 3x − 28 x2 + 3x − 11
slavikrds [6]

f(x)=x+7\\g(x)=x-4\\f(x)*g(x)=(x+7)(x-4)\\f(x)*g(x)=x^2+3x-28

So it's x^2+3x-28
