Answer:

A) 7 1/3

Step-by-step explanation:

A)  -2+12-2³÷2^0*3

-2+12-8÷1×3

-2+12-2 2/3

10-2 2/3

=7 1/3

B) Fractional exponent in this case makes it a square root (i dont remember how to do fractional exponents if the numerator is greater than 1)

√9+√25-8-8+3²

3+5-8-8+9

=1

C)  do brackets first 2³=8-6=2

1/2*3/5(2)+1/5

add the fifths together giving you 4/5

so it becomes

1/2*4/5*2/1

half of 2 is 1 so it becomes 1*4/5

=4/5
