287 = (2 x 100) + (8 x 10) + (7 x 1)
Just X to the second power minus nine. You can't subtract nine from x to the second power unless you know what x is.
To break it down: 1 x 10 = 10 10 to the power of 4 = (((10 x 10) x 10) x 10) 10 x 10 = 100 100 x 10 = 1,000 1,000 x 10 = 10,000 Answer: 10,000
1.0 x 10 to the power of 10 or 1.0 x 1010 can be written in standard form as 10,000,000,000 (10 billion).
1 (: cause x=1x to the 2nd power is the same as x2 (x squared) or x*x
10 to the second power is = 100, so 287
You add exponents, so it is 10 to the 4th power, which is 10000
287 = (2 x 100) + (8 x 10) + (7 x 1)
10 to the second power (102) is the same as 10 x 10, which equals 100.
Expanded Notation of 287 = (2 x 100) + (8 x 10) + (7 x 1).
When you multiply a number by itself, you get the "second power" of the number.That's also called the "square" of the number.Here are some examples:The second power of 5 is (5 x 5) = 25.The second power (square) of 10 is (10 x 10) = 100.The square (second power) of 6 is (6 x 6) = 36.The square of 3.1 is (3.1 x 3.1) = 9.61.
60!
10 to the 2nd power would be 100. 10 x 10 = 100.

50,600 10 to the fourth power = 10000 10 to the second power = 100 5 x 10,000 = 50,000 6 x 100 = 600
1 x 287, 7 x 41 = 287
