Evaluate integers raised to rational exponents

Full solution

Q.

2 x y+4 x y-\frac{1}{2} x y

Combine like terms: We are given the expression $2xy + 4xy - \left(\frac{1}{2}\right)xy$ . The first step is to combine like terms, which in this case are all the terms since they all contain the variable product $xy$ .
Add coefficients: To combine the terms, we add the coefficients of $xy$ together. The coefficients are $2$ , $4$ , and $-(\frac{1}{2})$ . $\newline$ Calculation: $2 + 4 - (\frac{1}{2}) = 6 - (\frac{1}{2}) = 6 - 0.5 = 5.5$
Write simplified expression: Now that we have the combined coefficient, we can write the simplified expression as $5.5xy$ .
