Matrix question help needed

kramer

The required matrix is:

$\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]$

Step-by-step explanation:

We need to apply elementary row operation -2R₂+3R₁ tothe matrix:

$A=\left[\begin{array}{ccc}-3&5&2\\8&-1&3\\\end{array}\right]$

Multiplying Row 2 with -2 and Row1 with 3 and adding,

-9 15 6

-16 2 -6

----------

-25 17 0

After applying this operation, Row 1 will be changed while Row 2 will remain same because we get -2R₂+3R₁ -> R₁

The required matrix is:

$\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]$

PLEASE HELP!!!!! What values complete each statement? Enter your answers in the boxes. (16‾‾‾√)2 = _ in simplest form. By the Po

mario62 [17]

We are given expression: $(\sqrt{16})^2$ .

Square root in exponent form is power $\frac{1}{2}$ .

Therefore, $\sqrt{16} = 16^{1/2}$ .

Now, replacing square root of 16 by $16^{1/2}$ in original expression we are given, we get

$(\sqrt{16})^2 = (16^{1/2})^2 = (16)^2/2 = 16$ .

Therefore,

<h3> $(\sqrt{16})^2$ = 16 in simplest form. By the Power of Power rule, $(16^{1/2})^2=16^{2/2}$ . So, $16^{1/2}$ must equal $\sqrt{16}$ in radical form.</h3>
