Which expression is equivalent to 32 ⋅ 3−5? fraction 1 over 3 to the power 3 fraction 1 over 3 to the power 7 fraction 1 over 3
mars1129 [50]
Given expression 3² × 3⁻⁵

We will apply the power rule x^m*x^n=x^{m+n}

3² × 3⁻⁵ = 3²⁺⁽⁻⁵⁾ = 3²⁻⁵ = 3⁻³

We will then apply the power rule x^{-n} =  \frac{1}{x^n}

3⁻³ = \frac{1}{3^3}

Final answer: \frac{1}{3^3}

Find an explicit formula for g(n)
Elina [12.6K]

Answer:

g(n) = 2n + 49

Step-by-step explanation:

The explicit formula for an arithmetic sequence is

g(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given the recursive formula

g(n) = g(n - 1) + 2 ← with d = 2 and a₁ = 51, then

g(n) = 51 + 2(n - 1) = 51 + 2n - 2 = 2n + 49 ← explicit formula
