Answer for 23 plz plz plz
den301095 [7]

Answer:

A₍ₙ₎ = - 74 + (n-1) x 6

Step-by-step explanation:

A₍ₙ₎ = A₍₁₎ + (n-1) x d

A₍₁₈₎ = 28 = A₍₁₎ + 17 x d  ..... (1)

A₍₄₀₎ = 160 = A₍₁₎ + 39 x d  .....(2)

(2)-(1)    132 = 22d

d = 6

A₍₁₎ = 28 - 17 x 6 = -74

formula: A₍ₙ₎ = - 74 + (n-1) x 6

4^5*7^10 RAISED TO SINGLE POWER
Westkost [7]
<h3>Answer:   4^15</h3>

Explanation:

The rule used is

a^b*a^c = a^(b+c)

Basically you add the exponents. This only applies if the bases are both the same. In this case, they're both 4 so the rule works out.

Using the rule, we get

a^b*a^c = a^(b+c)

4^5*4^10 = 4^(5+10)

4^5*4^10 = 4^15
