20 to the second power is more commonly known as 202 or 20 squared. Squaring is calculated by taking two of the number and multiplying them together. In this case, 20x20=400 and so 20 to the 2nd power is 400.
220 = 1,048,576
Four to the second power is 16 or four squared.
That depends what the value of T is.
That depends what the value of A is.

9 is.

3 to the second power has only one vaue, exactly 9. There is no least value.
That depends what the value of T is.
a to the b power means b lots of a, all multiplied together. Thus, 203 or "20 to the 3rd power" can be rewritten as 20x20x20. If this value is calculated it comes out as 8,000. Thus 20 to the 3rd power can be simply expressed as 8,000.
3 to the 2nd power plus 5 x 4 - 9 = 20 32 + 5 x 4 - 9= 9 + 20 - 9= 20
Without brand, model and condition, there is no way to answer your question. It could be $20 or $2 thousand.
91 to the 2nd power is 8,281.
