It's 393. You first solve what's in the inner paranthesis first. Then add 10. Than multiple by 3 and add 5. Once you've gotten the answer to the inner part, multiple by 3. Remember PEMDAS.

The answer is 393.
The rule is Always start from the inside (the numbers capsulated by most brackets) and move out (the numbers capsulated by least brackets or no brackets). You can solve this exercise as follows;
10+(4.8)=42
5+3[42]=131
3{131}=393.

Start from the inside and work your way out....
4x8=32
32+10=42
3x42=126
5+126=131
3x131=393

I got 69 off the top of my head.
How in the world are you people getting 393?
It's four minus eight on my screen.

3{5+3[10+(4.8)]}
= 3{5+3[14.8]}
=3{5+44.4}
=3 * 49.4
=148.2
or if 4 .8 meant 4*8,
then your answer would be...
3{5+3[10+32]}
=3{5+3[42]}
=3{5+126}
=3*131
=393

3{5+3[10-4]}
=3(5+3(6))
=3(5+18)
=3(23)=69
