24/30 = 12/15 = 4/5
this is the simplified form
You know

Squaring both sides gives

Then raising both sides to any integer power
gives

That is, any power of
where the power is a multiple of 4 will always be equal to 1.
So

But perhaps you mean to write 20+1 as the exponent, in which case

Answer:
4, 1, 6.
See explanation
Step-by-step explanation:
You are given the equation

First subtract
from both sides:

and multiply the equation by -1:

Now multiply (1) by 2:

At last, divide by 

Answer:
34 is the answer
Step-by-step explanation:
Expression (non-algebraic): 3+2
An equation: 2x +1 = 21
An inequality: 2x > 2+2
