How do you simplify these problems ?
Dmitry [639]

\bf ~~~~~~~~~~~~\textit{negative exponents}\\\\a^{-n} \implies \cfrac{1}{a^n}\qquad \qquad\cfrac{1}{a^n}\implies a^{-n}\qquad \qquad a^n\implies \cfrac{1}{a^{-n}}\\\\[-0.35em]\rule{34em}{0.25pt}\\\\\cfrac{2x^3y^3}{4y^2}\implies \cfrac{2}{4}\cdot \cfrac{x^3y^3}{y^2}\implies \cfrac{1}{2}\cdot x^3y^3y^{-2}\implies \cfrac{1}{2}\cdot x^3y^{3-2}\implies \cfrac{x^3y}{2}\\\\~\dotfill\\\\


\bf \left(\cfrac{x^{-8}}{y^{11}}  \right)^{-2}\implies \left(\cfrac{y^{11}}{x^{-8}}  \right)^2\implies \stackrel{\textit{distributing the exponent}}{\left( \cfrac{y^{11\cdot 2}}{x^{-8\cdot 2}} \right)}\\\\\\\cfrac{y^{22}}{x^{-16}}\implies y^{22}x^{16}\\\\~\dotfill


\bf \cfrac{(2x^3)(x^4)^2}{8x^{11}}\implies \cfrac{(2x^3)(x^{4\cdot 2})}{8x^{11}}\implies \cfrac{2x^3x^8}{8x^{11}}\implies \cfrac{2x^{3+8}}{8x^{11}}\implies \cfrac{2x^{11}}{8x^{11}}\\\\\\\cfrac{2}{8}\cdot \cfrac{x^{11}}{x^{11}}\implies \cfrac{1}{4}\cdot 1\implies \cfrac{1}{4}

What is the area of this compound shape?
Paraphin [41]

Answer:

139.36

Step-by-step explanation:

first you do 8*8 because that would be the area of the square part

8*8=64

then find the area of the semicircle

first the Radis of it is 4 because 8/2=4

A=3.14R^2/2

3.14*4^2/2

3.14*16/2

50.24/2

25.12

now because there are 3 of the semicircles you do

25.12*3

75.36

then you add the 64 from the square to get your answer

75.36+64

139.36

Why does 10-0 equal 10 but 0/10
Wittaler [7]
Because 10 to the power of 0 equals 10. But 0 to the power of 10 does not equal 10 becuase if you do 0 10 times then it would just be 0.

Pls help me . Eleven family members are going on a trip together. They have cars that fit only 4
Alinara [238K]

Answer:

3.

Step-by-step explanation:

Since there are 11 family members and only 4 people fit in a car, they will have to take 3 cars.

4 x 3 = 12,

Also, even though there is going to be 1 seat extra you cannot squeeze 3 people in. Ps. (Just a safety note) In real life it is illegal to drive with extra passengers in a vehicle.

Hope that helps. x
