2 answers:

7 0

When multiplying square roots, we simply multiply the values inside the square roots. So for example, let's look at the problem below.

√a · √a

So the square root of a times the square root of a equals the square root of a time a or √a² and the square root of a² is simply a.

Answer:

To multiply square roots, first multiply the radicands, or the numbers underneath the radical sign. If there are any coefficients in front of the radical sign, multiply them together as well. Finally, if the new radicand can be divided out by a perfect square, factor out this perfect square and simplify it.

Answer:

See explanations below

Step-by-step explanation:

a) 1/4+5/4

= (1+5)/4

= 6/4

= 3/2

b) 23/17+11/17

= (23+11)/17

= 34/17

= 2

c) 16/93+15/93

= (16+15)/93

= 31/93

= 1/3

d) 11/14+23/14

= (11+23)/14

= 34/14

= 17/7

e) 3/16+15/16

= (3+15)/16

= 18/16

= 9/8

f) 1 1/8 + 1 3/8

= 9/8 + 11/8

= (9+11)/8

= 20/8

= 5/2

g) 1 3/10+3 1/10;

= 13/10+31/10

= (13+31)/10

= 44/10

h) 2 3/5+3 2/5

= 13/5+17/5

= (13+17)/5

= 30/5

= 6

1.How many combinations are possible from the letters HOLIDAY if the letters are taken?

Lesechka [4]

Using the combination formula, it is found that:

1. A. 7 combinations are possible.

B. 21 combinations are possible.

C. 1 combination is possible.

2. There are 245 ways to group them.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Exercise 1, item a:

One letter from a set of 7, hence:

$C_{7,1} = \frac{7!}{1!6!} = 7$

7 combinations are possible.

Item b:

Two letters from a set of 7, hence:

$C_{7,2} = \frac{7!}{2!5!} = 21$

21 combinations are possible.

Item c:

7 letters from a set of 7, hence:

$C_{7,7} = \frac{7!}{0!7!} = 1$

1 combination is possible.

Question 2:

Three singers are taken from a set of 7, and four dances from a set of 10, hence:

$T = C_{7,3}C_{10,4} = \frac{7!}{3!4!} \times \frac{10!}{4!6!} = 245$

There are 245 ways to group them.
