Answer:

1. 6

2. 23

Step-by-step explanation:

logx+1 ( x^2 + 2x + 1)^3

= 3logx+1 ( x^2 + 2x + 1)

= 3 logx+1 (x + 1)^2

= 6 logx+1 (x + 1) Now the logx+1 x+1 = 1 so

The answer is 6.

log11 11^23

= 23 log11 11

As in question 1 log11 11 = 1

So the answer is 23.

What is x+y=10;y=x+10

[ Answer ]

$\boxed{\bold{X \ = \ 0, \ Y \ = \ 10}}$

[ Explanation ]

System Of Equations $\bold{\left \{ {X \ + \ Y \ = \ 10} \atop {Y \ + \ X \ = \ 10}} \right.}$

-----------------------------------

[Substitute] Y = X + 10

$\bold{\begin{bmatrix}x+x+10=10\end{bmatrix}}$

Isolate x for x + x + 10 = 10: x = 0

For y = 10

Substitute x = 0

Y = 0 + 10

0 + 10 = 10

y = 10

Solutions

X = 0

Y = 10

$\boxed{\bold{[] \ Eclipsed \ []}}$

ser-zykov [4K]

Answer:

$(x+2\sqrt{3} )(x+\sqrt{3} )$

Step-by-step explanation:

$x^2 + 3\sqrt{3}x + 6\\=> x^2 + \sqrt{3}x + 2\sqrt{3}x +6\\=> x( x+\sqrt{3}) + 2\sqrt{3}(x+\sqrt{3} )\\ => (x+2\sqrt{3} )(x+\sqrt{3} )$
