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

A. The probability is 1/36. There are 36 combinations of the first and second dice and only one of them is 2 - 4s.
B. 10/36. Ten of the options contain exactly 1 - 4.
C. The remaining 25/36 options do not include a 4.
Answer:
59 = (5x + 4)
x = 11
Step-by-step explanation:
59 = (5x + 4)
5x + 4 = 59
5x = 59 - 4
5x = 55
x = 55/5
x = 11
Answer:
44
Step-by-step explanation:
Since triangles are similar, so their corresponding sides would be in proportion.
Therefore,

<h3>
Answer</h3>
They are being multiplied by 2 each time.
