Write an expression that is equal to 8 using each number and symbol below exactly one time in the expression. Explain your thinking. 1 2 3 power of 3 + - ( )

[3+ 1- (2 )]³

Step-by-step explanation:

[3+ 1- (2 )]³= 8

[ 4-2]³=8

[2]³= 8

The smaller brackets around 2 indicate that minus is being multiplied by 2 making it -2. As the signs of 1and 3 are the same i.e + they both are added and the answer is 4. Now 4 has the +ve  sign and 2 has the -ve sign so 2 is subtracted from 4 and we get a +ve 2 . Now 2 raise to power 3 gives 8 which is the required number.

Only 2 raised to power 3 gives a 8. any other number like 3 or 1 raise to power does not give an eight.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
