Answer:
[tex]\frac{6 \times 5}{3} \times 7 +5[/tex]
Step-by-step explanation:
To express this problem using 7, 5, 6 and 3 without parenthesis, we have to use at least one number twice, because suing parenthesis is so much easier to express the result. So, the operations would be:
[tex]\frac{6 \times 5}{3} \times 7 +5=\frac{30}{3}\times 7 +5\\ 10\times 7 +5=70+5=75[/tex]
Therefore, the expression would be:
[tex]\frac{6 \times 5}{3} \times 7 +5[/tex]
