Assuming your original expression was 3√(27x¹⁸), the answer is 9x⁹√(3).
We split up the radicand into perfect squares. Once we do, we take out the things that were squared:

Answer:
we need a picture too
Step-by-step explanation:
Hello :
<span>A(-2, -5), B(-3, 2), and C (1, -2)
calculate : AB² , AC² ,BC²
</span> AB² = ( -3 +2 )² + ( 2 +5 )² =50
AC² = ( 1 +2 )² + ( -2 +5 )² =18
BC² = ( 1 +3 )² + ( -2 - 2 )² = 32
by petagor rule : AB² = AC² + BC²....(<span>ABC is a </span>right triangle in : C )
Step-by-step explanation:
8(5g+3)=0
40g+24=0
40g=0-24
40g=-24
divide both sides by 40
therefore, the answer is -0.6
I think so that both are b
