Answer:

2880 or 20!

Step-by-step explanation:

Whenever you have a number with a (!) after it, it means that the number is in factorial. So if you have a equation like 3!, it would be equal to 3·2·1. So in that case—

5! = 1·2·3·4·5

We can multiply this sequence of numbers simply.

1·2·3·4·5=120

Now, since we have the first factorial, we move on to the second.

4!=1·2·3·4

Again, we can multiply this sequence simply.

1·2·3·4=24

Now we move on to the final step. We have factoriazed the numbers, so we can substitute <em>those</em> in the equation.

120·24

Now we can finally multiply these 2 numbers to get your answer.

120·24=2880

That is the evaluation.

If you want to simplify the expression, multiply the numbers.

4!·5!=20!

What is the least common denominator for adding the fractions 4/15, 1/12, and 3/8
il63 [147K]
I think you want the least common multipule (exg LCM of 2,3,4 is 12)

so we find the factors and include all of them so like this

15=3 times 5
12=2 times 2 times 3
8=2 times 2 times 2

so to include all of them we include 3 2's, 1 3 and 1 5 or 2 times 2 times 2 times 3 times 5 or 8 times 15 or 4 times 30 or 120

the LCM is 120

so 4/15=32/120
1/12=10/120
3/8=45/120

add 32/120+10/120+45/120=(32+10+45)/120=87/120

Can some explain steps​
Mashutka [201]

Answer:

r = 3.

Step-by-step explanation:

16 = 10 + √(3r + 27)

√(3r + 27) = 6

Square both sides:

3r + 27 = 36

3r = 36 - 27 = 9

r = 3.

Check the result:

Left side of the equation = 16

Right side = 10 + √(9 + 27)

                  = 10 + √36 = 16
