Answer:

3 letters can be arranged in 26*25*24 = 15600 ways

3 digits can be arranged in 10 * 9 * 8 = 720 ways

So the total number is 15600 * 720 = 11,232,000

So I agree with the number that you obtained

What eqauls to 31.25

RSB [31]

125 = 5^3 = 25 * 5

$4 \cdot \sqrt{125} = 4 \sqrt{25 \cdot 5} = 4 \cdot 5 \sqrt{5} = 20\sqrt{5}$

The simplification you are trying to do involves finding the prime factorization of a number. Since 125 is not divisible by 2, move on to 3. 125 is also not divisible by 3, so move on to 5. Then 125/5 = 25, and 25/5 = 5, so 125 = 5^3. The prime factorization of 125 is 5^3.

I’m not sure if it would be A or B, does anyone know?

KengaRu [80]

B. It is vertically stretched by a factor of 4. If you had x^2 versus 4x^2, when x is positive and increasing, 4x^2 is increased by 4 for every value of x.
