This reduces nicely if you first notice that 16/81 = (2/3)^4.
Then use the properties of powers (of positive real numbers):
(16/81)^(3/4) = ((2/3)^4)^(3/4) = (2/3)^3 = 8/27
Answer:
1.8
Step-by-step explanation:
Answer:
a = 16
b = -6
Step-by-step explanation:
a + 2b = 4
2a + b = 26
2a + 4b = 8
2a + b = 26
3b = -18
b = -6
a + 2(-6) = 4
a - 12 = 4
a = 16
