Find the radical equivalent of 27^2/3 and compute it.<br> please help i'm taking a test.

AveGali [126]

Note that (a^b)^c=a^(bc) so in this case we have:

(27^(1/3))^2 the cube root of 27=±3

(±3)^2 and ±3^2=9

So the equivalent expression is 9 or if you need an exponent 9^1 :)

I am assuming that you meant 27^(2/3)

express each of the following as product of its prime factors, giving your answer in expanded form. a) 24. b) 63. c) 84. d) 150

Alborosie

To answer this question, you can use a factor tree, or the table thing (I forgot what it’s called.)
You divide the number by one of its PRIME factors, until there is only one left. The numbers you divided it by are written as shown.
Hope this helps. :)

Y=3x²+3x+1,find the value of the discrimination

Rufina [12.5K]

Answer:

Step-by-step explanation:

a = 3

b = 3

c = 1

Discriminate = sqrt(b^2 - 4ac)

Discriminate = sqrt(9 - 4*3*1)

Discriminate = sqrt(9 - 12)

Discriminate = sqrt(-3)

What negative value means that there are no real roots and the y intercept = 1. You should always graph this kind of question, which I am doing for you. I use Desmos which is a very handy program.

You should notice that the minimum is above the x axis. That means there are no real roots, just as the discriminate tells you.
