Answer:
500
Step-by-step explanation:
So first off we know that there are 9000 (9k) natural 4-digit numbers -->
we solve using permutations so we can set the problem up like this
1 2 3 4
4 x 5 x 5 x 5 = 100 x 5 = 500
Reasoning:
So the reason we can do it like this is because -->
even numbers are: 0, 2, 4, 6, 8
ALL DIGITS MUST BE EVEN --> calculate using permutations simply makes it 5^4 but that's NOT our answer. Since the first digit can't be zero, we have -->
4, 5, 5, 5 respectively
Multiply this (by rule of permutations) to get, => 20 x 5 = 100
100 x 5 = 500
Thus, we have our answer of 500

Answer: b = √6
Step-by-step explanation: Use the Pythagorean Theorem to solve this.
a² + b² = c²
Plug in your values:
2√3² + b² = 2b²
When a square root is squared, the square root is cancelled out so you will be left with this:
2(3) + b² = 2b²
Subtract b² from both sides so you’re left with:
6 = b²
Now, to get rid of the square, just square root both sides:
√6 = √b²
Since the √6 is not a perfect square, leave it in the radical. Then, you get your answer:
b = √6
The answer is 4 My dude because 2+2=4
