Question

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

Answer 1

Answer: 10/3

Explanation:

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

$( \frac{1}{3} )(4+18)-2^2$

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

1) Solve the parenthesis:

=>      $\frac{1}{3} .22-2^2$

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

=>      $\frac{1.22}{3.1}-4 = \frac{22}{3}-4$


3) Subtract 4 from the fraction 22/3

$\frac{22}{3} -4= \frac{22-4.3}{3} = \frac{22-12}{3} = \frac{10}{3}$
