PLS I REALLY NEED HELP AND 50 pointd

I think you're doing one of these

√asquare root√a ⋅ √a  = a√9 = ±3

3√acube root3√a ⋅ 3√a  ⋅ 3√a  = a3√8 = 2

4√afourth root4√a ⋅ 4√a  ⋅ 4√a  ⋅ 4√a  = a4√16 = ±2

n√an-th root (radical)n/afor n=3, n√8 = 2

well let me know :)

10-2 is 8

Step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
