What exponential expression is equal to 2 to the negative 5th power • 2 to the 8th power ?

2³

Step-by-step explanation:

Written in numerical form:

2⁻⁵ · 2⁸

Since both exponents have the same base, one of the exponent rules apply. When multiplying exponents with the same base, you add the exponents.

xᵃ · xᵇ = xᵃ⁺ᵇ

2⁻⁵ · 2⁸

= 2⁽⁻⁵⁾ ⁺ ⁸

= 2³   Simplified exponent form

= 8    Most simplified form

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.

answer is a.
