Answer:
3a - b = 1
Step-by-step explanation:
a = (2-3)
b = (1-5)
Substitute the values of a and b to the 3a-b.
3(2-3) - (1-5)
6-9 - (-4)
6 - 9 + 4
-3 + 4
= 1
Therefore, 1 is the answer.
Answer:
157
Step-by-step explanation:
Simplify the following:
125 - (5 - 9)^3/2
5 - 9 = -4:
125 - (-4)^3/2
(-4)^3 = (-1)^3×4^3 = -4^3:
125 - (-4^3)/2
4^3 = 4×4^2:
125 - (-4×4^2)/2
4^2 = 16:
125 - (-4×16)/2
4×16 = 64:
125 - (-64)/2
