Answer:
+
Step-by-step explanation:
We sure can write 2^2/5+ 3^1/10 as 
// use the
to transform the expression
Convert
to
=
(here a = 2, n = 5, m = 2)
Then convert
to
=
(here a = 3, n = 10, m = 1)
Now we get
=
+
. This is the simplified form, which is the answer.
Answer:
-1/5
Step-by-step explanation:
When a line is perpendicular to another line, it's gradient will be a reciprocal.
To calculate the reciprocal of a number you have to flip the fraction the other way around.
So, in the case our current gradient is 5/1 (5/1 is the same as just 5) and we need to flip in over to get 1/5, which is our new gradient.
The final step is to make the number negative because the line is going down. This gives us the final answer of -1/5.
Use the identity:
tan^2 = sec^2 - 1
