Answer:

Step-by-step explanation:

Square root of 2 is irrational. This has been proven by the Pythagoreans (there is a simple proof of that).

pi is also known to be irrational although the proof is a bit more demanding.

Square root of 10 can be written as a product of square root of 5 and square root of 2, which themselves are irrational. Any product involving an irrational number is irrational

Square root of 16 = 4. 4 can be written as a fraction 4/1, or 8/2, 16/4, etc. and therefore is rational by definition.

Galina-37 [17]

Step-by-step explanation:

$= { ({16}^{ \frac{3}{2} } )}^{ \frac{1}{2} }$

$= { ({( {2}^{4}) }^{ \frac{3}{2} } )}^{ \frac{1}{2} }$

$= {2}^{4 \times \frac{3}{2} \times \frac{1}{2} }$

$= {2}^{ \frac{12}{4} }$

$= {2}^{3}$

$= 2 \times 2 \times 2$

$= 8$

-1(x+2)=2(3x-6) Please solve

Korvikt [17]

$-1(x+2)=2(3x-6)$
$-1(x+2)=2(3x-6)$ distributhing -1 through parantheses
$-1x+(-1)*2=2(3x-6)$
$-x-2=2(3x-6)$ distributhing 2 through parantheses
$-x-2=2*3x-2*6$
$-x-2=6x-2*6$
$-x-2=6x-12$ add x
$-2=6x-12+x$
$-2=7x-12$ add 12
$-2+12=7x$
$10=7x$ divide by 7
$x= \frac{10}{7}$
Answer : x= 1 3/7
