Question

Evaluate the expression 1/3 (4+18)-2 2nd degree

Answer 1

Answer: 10/3

Step-by-step explanation:

I will rewrite the expression using the math editor just to make it more understandable.


`( (1)/(3) )(4+18)-2^2`

Now, I will show the solution step-by-step

1) Solve the parenthesis:

=>
`(1)/(3) .22-2^2`

2) Calculate the product of the fraction 1/3 times number 22 and rais 2 to the power 2:

=>
`(1.22)/(3.1)-4 = (22)/(3)-4`


3) Subtract 4 from the fraction 22/3


`(22)/(3) -4= (22-4.3)/(3) = (22-12)/(3) = (10)/(3)`
