Answer:

  \dfrac{a+b}{a}

Step-by-step explanation:

There is nothing to solve. Perhaps you want to simplify the expression.

  \dfrac{a^{-1}+b^{-1}}{b^{-1}}=\dfrac{b(a^{-1}+b^{-1})}{b(b^{-1})}=\dfrac{b}{a}+1=\boxed{\dfrac{a+b}{a}}

_____

The applicable rules of exponents are ...

  b^-1 = 1/b

  (a^b)(a^c) = a^(b+c)

Please help me give me the answer
patriot [66]

Answer:

a) Area of a rectangle = length × width

Area = 6138cm²

Width = 62m

length = Area / width

length = 6138/62

length = 99m

b) Perimeter of a rectangle = 2l + 2w

l = length

w = width

perimeter = 338m

length = 98m

338 = 2(98) + 2w

2w = 338 - 196

2w = 142

w = 71m

width = 71m

Hope this helps.
