5/2 to the second power means 5/2 squared. "Squared" means multiplied by itself. We would write this as (5/2)2. This means (5/2) * (5/2). 5/2 * 5/2 = 25/4 = 6.25.
No
No.
Yes. 5 and 20 are divisible by 5, so you can simplify 5/20 to 1/4.
5*root(21^2) = 5*21 = 105
No
5/x4
don't think you can simplify it
answer is p/5. problem: {[(p^2)-3p]/[(p^2)-6p+9]}/{20/(4p-12)}

its like 5 to the second power. 52 what ever square it is you multiply it by its self example 3 squared =3 to the power of 3= 3x3=9
Yes. 5 and 20 are divisible by 5, so you can simplify 5/20 to 1/4.
The term "squared" refers to multiplying a number by itself, which in mathematical terms is represented as raising that number to the power of two. Thus, when we say "five squared," we mean (5^2), or (5 \times 5). The use of "squared" originates from geometry, where the area of a square with side length (5) is calculated as (5) multiplied by itself. This terminology has carried over into algebra and mathematics more broadly.
