Me with math ): its very urgent
1. which of the following is irrational?
a. square root of 6
b. square root of 0.16
c. square root of 900
d. square root of 25
2. the value of square root of 13 is between
a. 2 and 3
b. 3 and 4
c. 4 and 5
d. 5 and 6

Here's my step-by-step explanation:

1) Let's go through the letters to see which ones are rational. If a number is irrational, then it's a decimal with no pattern. In other words, it cannot be expressed as a fraction.

D, the , is 5. Because 5 can be expressed as a fraction 5/1, this is incorrect.

C, the , is 30. Because 30 can be expressed as a fraction 30/1, this is incorrect.

B, the , is 0.4. Although 0.4 is a decimal, it can still be expressed as a fraction 4/10 or 2/5, so this is incorrect.

A is the . There's no number that squares to 6 and immediately comes to mind, and when you put it through the calculator, it's definitely not a clean number (2.4494897...). Because that cannot be expressed as a fraction, this is correct.

2) Let's start from 0 and square numbers until we pass 13. Try it on your own as well!

0^2 = 0

1^2 = 1

2^2 = 4

3^2 = 9

4^2 = 16

5^2 = ...wait, we passed 13.

Since 13 is between 9 and 16, the square root of 13 is between the square root of 9 and the square root of 16. So the square root of 13 is between 3 and 4.

Hope this helps, let me know if I made a mistake or if you have any questions!

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
