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
