Ans = _______


Sagot :

To find the value of the expression [tex]\(3 \times[64 \div(13-5)-4] \times 42 \div 6\)[/tex], we will evaluate it step-by-step following the order of operations: parentheses first, then division and multiplication from left to right.

1. Evaluate the expression inside the parentheses:
[tex]\[ 13 - 5 = 8 \][/tex]

2. Division within the brackets:
[tex]\[ 64 \div 8 = 8.0 \][/tex]

3. Subtract 4 from the result of the division:
[tex]\[ 8.0 - 4 = 4.0 \][/tex]

4. Multiply the result by 3:
[tex]\[ 3 \times 4.0 = 12.0 \][/tex]

5. Multiply the result by 42:
[tex]\[ 12.0 \times 42 = 504.0 \][/tex]

6. Finally, divide the result by 6:
[tex]\[ 504.0 \div 6 = 84.0 \][/tex]

Thus, the final result is:
[tex]\[ \boxed{84.0} \][/tex]
