SIMPLIFY 81 TO THE 1/3 POWER

Mathematics

81^1/3. We know that 81 is 3^4, meaning 3 x 3 x 3 x 3 is 81. So (3^4)^1/3 is 3^4/3, which is 3 * (cubed root of 3).

Okay lets see 81^1/3 means that you are multiplying by a third. but you can also turn it into a division problem as simple as putting 81 in the place of the 1. Now the problem looks like this: 81/3. so if you divide 81 by 3 you get 27. check the ,mat by doing it backwards. multiply 27 by 3 and see what you get. it should be 81.

Please help me..............................

Answer:

y = 12

Step-by-step explanation:

∵ m∠ABC = 40

∵ BD ray is the bisector of ∠ABC

∴ m∠ABD = m∠CBD = 20

In 2 Δ BAD and BCD:

∵ m∠BAD = m∠BCD = 90°

∵ m∠ABD = m∠CBD = 20°

∵ BD is a common side in the two triangles

∴ ΔABD congruent to ΔCBD⇒(AAS)

∴ AD = CD

∴ 3y + 6 = 5y - 18

∴ 5y - 3y = 6 + 18

∴ 2y = 24

∴ y = 24/2 = 12

Can somebody explain this to me when 2du = 16xdx ???
tamaranim1 [39]
When you set u=4x^2+4, you end up with the differentials \mathrm du=8x\,\mathrm dx. Multiplying both sides by 2 gives 2\,\mathrm du=16x\,\mathrm dx.

Then the integral is

\displaystyle\int_0^1\frac{16x}{(4x^2+4)^2}\,\mathrm dx=\int_4^8\frac2{u^2}\,\mathrm du=-\frac2u\bigg|_{u=4}^{u=8}=-2\left(\frac18-\frac14\right)=\frac14

Answer:

  A.  57 7/9 ft³

Step-by-step explanation:

The volume of a rectangular prism (cuboid) is the product of its dimensions.

  V = LWH

  V = (4 1/3 ft)(3 1/3 ft)(4 ft)

If you drop the fractions, this becomes ...

  V = (4 ft)(3 ft)(4 ft) = 48 ft³

You know the fractions add some amount to this, so you know the volume will be somewhat larger than 48 ft³. The only reasonable choice is A: 57 7/9 ft³.

__

If you feel the need to compute the volume exactly, you can do so using improper fractions.

  V = (13/3 ft)(10/3 ft)(4 ft) = 520/9 ft³ = 57 7/9 ft³
