Answer: El número es 902 en el sistema decimal.

Step-by-step explanation:

Supongo que tenemos el número:

32012 en base 4, y lo queremos representar en base decimal.

Entonces, usando la regla general, podemos escribir este número como:

unidades*base^0 + decenas*base^1 + centenas*base^2......

Es decir, acá tenemos:

2*4^0 + 1*4^1 + 0*4^2 + 2*4^3 + 3*4^4 = 902

El número es 902 en el sistema decimal.

Q2.<br>a) Is the equality √a^4 = a valid for all values of a? Explain.<br>

allochka39001 [22]

Answer:

The equality is only true for $a = 0\ and\ 1$ , not for all values

Step-by-step explanation:

Given

$(\sqrt a)^4 = a$

Required

Determine if it is valid

$(\sqrt a)^4 = a$

Evaluate the exponent

$(a^\frac{1}{2})^4 = a$

$a^\frac{1*4}{2} = a$

$a^2 = a$

Rewrite as:

$a^2 - a = 0$

Factorize

$a(a- 1) = 0$

$a =0\ or\ a - 1 = 0$

$a =0\ or\ a = 1$

<em>The equality is only true for </em> $a = 0\ and\ 1$ <em>, not for all values</em>

Can someone please help me its urgent!!!!!!!!!!<br> 3x + 11 = 3x - 11

user100 [1]

Answer:

$\Large\boxed{\mathsf{\Rightarrow NO\quad SOLUTIONS}}$

Step-by-step explanation:

<h3><u>TO SOLVE:</u></h3>

Isolate by the x on one side of the equation.

<h3><u>SOLUTIONS:</u></h3>

First, subtract 3x from both sides.

$\displaystyle \Rightarrow \mathsf{3x+11-3x=3x-11-3x}}$

Solve.

$\displaystyle \mathsf{11=-11}$

Sides are NOT equal.

$\Large\boxed{\mathsf{\Rightarrow THERE \quad ARE \quad NO \quad SOLUTIONS}}}$

Therefore, there are no solutions.
