The answer is A
Have to add characters to get to 20
First expression
=> 3 x 3 x 3 x 3 x 3 – In this expression, we multiplied 3 5 times and the product is 243
Second expression
=> 3 ^ 5 , in where ^ read as raised to the power. , the product is also 243
Third expression
=> 3^2 x 3 ^3
=> (3 x 3) x (3 x 3 x 3)
=> 9 x 27, the product is also equals to 243.
Answer:

Step-by-step explanation:
The given function is

To find g(n-7), we substitute x=n-7 to obtain;

Expand the parenthesis to obtain;

Simplify:

Greater than 1.Because 1.25-0.25=1.23.That's it.
Irrational numbers don't end
they can't be written in form a/b
obvoisly, 58.25 ends and it can be written as 58.25/1
(repeating decimals can be written in a/b form, it just takes work to find)
false, 58.25 is NOT irrational
