Answer:

see explanation

Explanation:

in (1) and (2) use the rule of exponents


a^(-m) =
(1)/(a^(m) ) , then

(1)


H^(-6) =
(1)/(H^(6) )

(2)


N^(-3) =
(1)/(N^(3) )

question (3) involves expanding a binomial

(B - 4)²

= (B - 4)(B - 4)

each term in the second factor is multiplied by each term in the first factor, that is

B(B - 4) - 4(B - 4) ← distribute both parenthesis

= B² - 4B - 4B + 16 ← collect like terms

= B² - 8B + 16
