Answer:

D. 54/n¹¹

Step-by-step explanation:

(6n⁻⁵)(3n⁻³)²

<em>Note that (ax)ᵇ=aᵇxᵇ</em>

(6n⁻⁵)(3²)(n⁻³)²

(6)(n⁻⁵)(9)(n⁻³)²

54(n⁻⁵)(n⁻³)²

<em>Note that (xᵃ)ᵇ=xᵃᵇ</em>

54(n⁻⁵)(n⁻³⁽²⁾)

54(n⁻⁵)(n⁻⁶)

54(n⁻⁵)(n⁻⁶)

54(n⁻⁵)(n⁻⁶)

<em>Note that (xᵃ)(xᵇ)=xᵃ⁺ᵇ</em>

54(n⁻⁵⁻⁶)

54n⁻¹¹

<em>Note that x⁻ᵃ=1/xᵃ</em>

54/n¹¹

Find the lateral and surface area of each cone
Sophie [7]

Answer:

\large\boxed{L.A.=153\pi\ mm^2}\\\boxed{S.A.234\pi\ mm^2}

Step-by-step explanation:

The formula of a lateral area of a cone:

L.A.=\pi rl

r - radius

l - slant height

The formula of a surface area of a cone:

S.A.=\pi r^2+\pi rl

We have r= 9mm and l = 17mm. Substitute:

L.A.=\pi(9)(17)=153\pi\ mm^2

S.A.=\pi(9^2)+153\pi=81\pi+153\pi=234\pi\ mm^2

Express each answer in simplified radical form. . 18√5−12√5=?
leonid [27]

Answer: Hello mate!

our equation is 18√5−12√5 and we want to simplify it.

Simplification is triyng to "eliminate" all the roots (if possible). In our equation we have a square root of 5, wich is a problem, but let's se wat we can do:

18√5−12√5

= (18 - 12)√5

= 6√5

and we can not simplify furthermore, because the √5 cant be simplifyed.
