Multiplication with rational exponents

Full solution

Q. Evaluate:

20 - \frac{1}{3} * ( - 5) -

\frac{- 36}{- 9}

Divide $-36$ by $-9$ : Now, divide $-36$ by $-9$ . $\frac{-36}{-9} = 4$
Subtract from $-5$ : Next, subtract the result from $-5$ . $\,-5 - 4 = -9$
Replace in curly brackets: Replace the simplified expression inside the curly brackets. $\newline$ $20 - \frac{1}{3} \times \{-9\}$
Multiply by $1$ / $3$ : Multiply $-9$ by $\frac{1}{3}$ . $\frac{1}{3} \times -9 = -3$
Subtract from $20$ : Finally, subtract the result from $20$ . $\newline$ $20 - (-3) = 20 + 3 = 23$
