Which expression is the simplest form of (27x^-9)^1/3?

lana [24]

$\sqrt[n]{a^m}=a^\frac{m}{n}\\\\\sqrt[n]{a}=a^\frac{1}{n}\\\\(a^n)^m=a^{nm}\\\\(a\cdot b)^n=a^n\cdot b^n\\\\(27x^{-9})^\frac{1}{3}=27^\frac{1}{3}(x^{-9})^\frac{1}{3}=\sqrt[3]{27}\cdot x^{-9\cdot\frac{1}{3}}=3x^{-3}=\dfrac{3}{x^3}$

What is the missing constant term in the perfect square that starts with x2+18xx^2+18xx2+18xx, squared, plus, 18, x ?

katrin2010 [14]

Answer:

Step-by-step explanation:

Given the expression: $x^2+18x$

To make it a perfect square, we follow the following steps.

Divide the coefficient of x by 2

Coefficient of x=18, 18/2=9

Square It

9 X 9=81

Add it to the expression

$x^2+18x+81$

This is written as a perfect square as: $(x+9)^2$

The constant term required therefore is 81.
