Question

4[8-{5\4}+(5+7)-7]

Answer 1

Answer on Question #48337 – Math – Algebra

$$4[8 - \{5\setminus 4\} + (5 + 7) - 7]$$

Solution

We need to solve this step by step:

1) $5 + 7 = 12$

2) $\{5\setminus 4\} = 0.25$ (because $\{\}$ function is a function of fractional part and $5/4 = 1.25$)

3) $8 - \{5\setminus 4\} = 8 - 0.25 = 7.75$

4) $7.75 + 12 - 7 = 12.25$

5) $12.25 * 4 = 49$

So:

$$4[8 - \{5\setminus 4\} + (5 + 7) - 7] = 49$$
