What is the simplest form of 4 square root 81x^8y^5?

olasank [31]

Firstly,
thanks for posting this.

81 = 9x9 or 9 squared so at this stage I'm guessing the last two.
x^ 8 = (x^ 4) x (x^ 2) (its called the multiplication rule of indices).
Okay I have approx 14 mins to answer.
No panic
√ 81.x^8 x √ y^5
√ (9x^2 x 9x^6) x √ y^5
= 9x x √ 9x^6 x √ y^5
did I just gain time?
√ 9x^6 = √ 3x ^3 x √ 3x ^ 3
or 2 . √ 3x^3. √ y^5
more time
okay, so that wasnt successful.
√ 9x^6 =√ (3x^2) x √ (3x^4)

A function f is differentiable for all values of x in [0,6], and the graph with equation y=f(x) has a local minimum point at (2,

MrRa [10]

Step-by-step explanation:

The slope of tangent line at a max or a minimum is 0,.

So using point slope formula.

$y - 4 = 0(x - 2)$
