It’s f4=8 for the neg power

Use Inverse operations to solve the expression. Enter your answer in simplest form. y 1 =8 16

vredina [299]

So we are trying to get the “y” alone, so to undo the division by -8, we will multiply both sides by -8, then simplify.

(-8) y/(-8) = (-8) 1/16

y = -8/16

and simplified:

y = -1/2

Anyone know how to solve this??

Tom [10]

$Given : \frac{(x^\frac{2}{5})^9\;.\;(x^\frac{-4}{15})}{x^\frac{1}{3}}$

$\implies {(x^\frac{18}{5})\;.\; (x^\frac{-4}{15})}\;.\;(x^\frac{-1}{3})$

$\implies x^(^\frac{18}{5} ^-^\frac{4}{15}^-^\frac{1}{3}^)$

$\implies x^(^(^\frac{54 - 4}{15}^)^-^\frac{1}{3}^) = x^(^(^\frac{50}{15}^)^-^\frac{1}{3}^) = x^(^(^\frac{10}{3}^)^-^\frac{1}{3}^) = x^(^\frac{9}{3}^) = x^3$

$\implies x^k = x^3$

$\implies k = 3$

Volume of a Cone Formula: $\displaystyle V = \frac{1}{3} \pi r^2h$

r is radius
h is height

Step-by-step explanation:

Step 1: Define

Radius r = 4

Height h = 21

Step 2: Find Volume

Substitute in variables [Volume of a Cone Formula]: $\displaystyle V = \frac{1}{3} \pi (4)^2(21)$
Evaluate exponents: $\displaystyle V = \frac{1}{3} \pi (16)(21)$
Multiply: $\displaystyle V = \frac{16 \pi}{3}(21)$
Multiply: $\displaystyle V = 16 \pi \cdot 7$
Multiply: $\displaystyle V = 112 \pi$

What's the volume of the cylinder

alisha [4.7K]

Answer:201.06

Step-by-step explanation: The way I found the answer is by taking the radius of the equation which is 4 and multiplying it to the power of 2 then I took the height which is 8 and multiplied it to pie which equals to 201.06

Hope this helps!
