Jenna is correct.  This is because the square root of 2 is an irrational number.  And if the number is a prime number, the answer is less likely to have a rational square root.

Answer: Jenna is correct.

Step-by-step explanation:

We can prove this statement with help of two examples.

Since we know that 64 is the rational number.

And, the square root of 64 is \sqrt{64}.

Which is equal to 8 or -8.

And, they are integers, and we know that the integer are always a rational number.

Therefore \sqrt{64} is a rational number.

And, If we take a number 2 which is a rational number.

Since, when we do square root of 2, we get √2.

And, √2 is a irrational number.

Thus, we can say that we can obtain a rational or irrational number after doing the square root of rational number.

Therefore, Jenna is correct.

$e\cdot e^x -e^{-2}=-2$

$\implies e^{x+1}=e^{-2}-2$

note that RHS is negative. (because e with negative exponent is less than 1)

and LHS is always positive.

so there cannot be any solution

PLEASE SHOW WORK AND HELP EXPLAIN: 12.42 divided by 4.6
Anni [7]

Answer:

12.42 = 1242 / 100;

4.6 = 46 / 10;

12.42 ÷ 4.6 = (1242 / 100) ÷ (46 / 10 ) = (1242 / 100) x (10 / 46 ) = ( 1242 / 46  ) x ( 100 / 10 ) =  27 x 10 = 270;
