Answer:

5x^{-10}z^{10

Step-by-step explanation:

Given

\frac{15x^{-3}z^5}{3x^7z^{-5}}

Required

Evaluate

\frac{15x^{-3}z^5}{3x^7z^{-5}}

Start by dividing 15 by 3

\frac{5x^{-3}z^5}{x^7z^{-5}}

Apply the following law of indices on indices x and z

\frac{a^m}{a^n} = a^{m-n

So, the expression becomes:

5x^{-3-7}z^{5-(-5)

5x^{-3-7}z^{5+5

5x^{-10}z^{10

Use the pythagoras theorem to find the number of blocks between Shakillah's and Reyna's house
= sqrt (12^2+ 5^2) = aqrt 169 = 13 blocks
distanc,e from school to Shaquilla's house  = 12 - 0 = 12 blocks
  ..   ..   ..   ..     ..   ...  ..    Reyna's  house    = 5 -0 = 5 blocks

So total number of blocks in entire trip  = 5 + 12 + 13 = 30

Lunna [17]

It costs $ 30240 to stain floor of the entire room

<em><u>Solution:</u></em>

<em><u>Given that,</u></em>

Sgt. Merritt has bought a house now that his tour of duty is up

He wants to stain the wood floors of the living room, which measure 18 x 14

Therefore,

length = 18 yards

Width = 14 yards

<h3><u>Find the area:</u></h3>

Area = length \times width\\\\Area = 18 \times 14\\\\Area = 252

Thus area of wood floors is 252 square yards

<h3><u>How much will it cost to stain floor of the entire room?</u></h3>

The stain costs $120 per square yard

Cost = 252 \times 120\\\\Cost = 30240

Thus it costs $ 30240 to stain floor of the entire room
