What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio
aalyn [17]

Answer:

  StartFraction 6 Over 5 x Superscript 10 Baseline EndFraction

Step-by-step explanation:

Apparently you want to simplify ...

  \sqrt{\dfrac{72x^{16}}{50x^{36}}}

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  1/a^b = a^-b

  (a^b)^c = a^(bc)

__

So the expression simplifies as ...

  \sqrt{\dfrac{72x^{16}}{50x^{36}}}=\sqrt{\dfrac{36}{25x^{36-16}}}=\sqrt{\dfrac{36}{25x^{20}}}\\\\\sqrt{\left(\dfrac{6}{5x^{10}}\right)^2}=\boxed{\dfrac{6}{5x^{10}}}

Tony has 6 rectangle shaped pieces of wood. He places them down right next to each other. The dimensions of the wood shape are 2
sleet_krkn [62]

Answer: The whole area of all the wood is 36

Step-by-step explanation:

The formula for area of a rectangle is length times width. A=lw

You plug the numbers into the formula: A=2*3 = 6

The area for one piece of wood is 6 ft

If you take multiply one area of wood by the amount of wood - you get the whole area amount of all the wood. So 6*6 = 36.
