I need help with these two math problems. i have been trying those for two hours. Can't find the answer.

use grouping symbols to make each equation true.

1/2*2^3/2*4/8*4/2=1/2

64-5*1+4/8+5=3

*= multiplication

is there any qucik way or any trick to solve these problems quickly because of test timing. immidiate answer would be very helpful

• math -

[(1/2)*(2^3)/2]* [4/(8*4/2)]
= [(1/2)*4]*(4/16) = 1/2

[64-5*(1+4)]/(8+5) = 39/13 = 3
