Perimeter of rectangle = all sides added
= 3+3+7+7 =20


volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257

area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15

volume of pyramid = base height x base width x height / 3
= 300

side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5

Which equation justifies why nine to the one third power equals the cube root of nine?
AVprozaik [17]

Answer:

nine to the one third power all raised to the third power equals nine raised to the one third times three power equals nine

Step-by-step explanation:

we know that

The <u><em>Power of a Power Property</em></u> , states that :To find a power of a power, multiply the exponents

so

(a^{b})^{c}=a^{b*c}

In this problem we have

9^{\frac{1}{3}} =\sqrt[3]{9}

Remember that

\sqrt[3]{9}=9^{\frac{1}{3}}

Raise to the third power

[9^{\frac{1}{3}}]^3

Applying the power of power property

9^{\frac{3}{3}}

9^{1}

9

therefore

nine to the one third power all raised to the third power equals nine raised to the one third times three power equals nine
