Answer:

See Explanation

Step-by-step explanation:

Required

Use any 4 consecutive digit from 0 to 9 to form an expression that equals 1 through 30

There is no formula to answer this question. All we need to do is, apply trial by error method to for each expression.

Possible expression and their results are:

- 1  + 2 * 3 - 4 = 1

1 + 2 + 3 - 4 = 2

0 * 3 + 1 + 2 = 3

0 * 2 + 1 + 3 = 4

1 * 3 + 4 - 2 =5

0 + 1 + 2 + 3 = 6

0 + 1 + 2 * 3 = 7

3 + 4 - 5 + 6 = 8

1 * 2 + 3 + 4 =9

1 + 2 + 3 + 4 =10

2^3 + 4 - 1 = 11

5 + 6 - 7 + 8  =12

4^2 - 3 * 1 = 13

2 + 3 + 4 +5=14

2 * 3 +4 + 5 = 15

4 * (3 - 1)^2 = 16

3 * 5 + 4/2 = 17

3 + 4 + 5 + 6 = 18

2 + 3 * 4 + 5 = 19

3 + 2^4 + 1 = 20

4 * 5 - 6 + 7 = 21

4 + 5 + 6 + 7 =22

3 * 4 + 5 + 6 = 23

5^2 -4 + 3 = 24

2^5 - 4 - 3 = 25

5 + 6 + 7 +8 = 26

\frac{3^4}{5-2} =27

5 * 4 + 2^3 = 28

3 + 4 * 5 + 6 = 29

6 + 7 + 8 +9 = 30

What is the answer of this attachment:
Solnce55 [7]

Answer:

(B) 2

Step-by-step explanation:

=> \frac{\sqrt{32}+ \sqrt{48} }{\sqrt{8}+\sqrt{12}  }

=> \frac{4\sqrt{2}+4\sqrt{3}  }{2\sqrt{2}+2\sqrt{3}  }

=> \frac{4(\sqrt{2}+\sqrt{3})  }{2(\sqrt{2}+\sqrt{3)}  }

Cancelling \sqrt{2}+\sqrt{3}

=> \frac{4}{2}

=> 2
