Answer: 2.25
Step-by-step explanation:
Assuming you mean sqrt(-144, we can use some properties of square roots to figure this out. sqrt(x*y) = sqrt(x) * sqrt(y)
We have sqrt(-1*144) = sqrt(-1) * sqrt(144). That would be i * 12, which is 12i.
Answer:
a) (x/7)^1/9=y
Step-by-step explanation:
f(x) = 7x^9
x/7= 7y^9/7
(x/7)^1/9=(y^9)^1/9
(x/7)^1/9=y
f^-1(x) is a fuction because it passes the vl test
892 x 18 = 16,056
First multiply 2 with 18 and do the same with 9 and 8 then multiply 2 with one and do the same with 9 and 8 then add up the two sums which give you 16,056
