Using exponents, see if you can find the pattern in the numbers
2
4
8
16
The first thing you notice is that from 2 to 4, it gets doubled. 4 to 8 is doubled again, and 8 to 16 is another doubling. This means we are multiplying each number by 2 to find the next number in the pattern.
Can you guess what the next number after 16 might be? If you double 16 (16 *2)... 32!
Since we're multiplying things by 2, I'm going to write each number as a multiple of 2.
2 = 2
4 = 2 * 2
8 = 2 * 2 * 2
16 = 2 * 2 * 2 * 2
See the pattern?
In order to express the numbers as exponents, count how many 2's you have for each number. and then write 2 to the (how many 2's you counted) power.
2 = 2 = 2 to the 1 power (although we almost never write 2^1, just 2.)
4 = 2 * 2 = 2^2
8 = 2 * 2 * 2 = 2 ^ 3
Can you figure out the last one?
16 = 2 * 2 * 2 * 2 = 2 ^?

How do you write 16 in exponents?
Several ways :- 161 42 24
What are two ways to write the number 16 using exponents?
4^2 = 4x4 = 16 2^3 = 2x2x2 = 16 in other words the answer is two to the power of three or four to the power of two... 4^2 2^3

How do you write 4x4 in exponents?
There are really infinitely many ways to write 4x4 in exponents, but consider what 4x4 really means and what an exponent is. First, an exponent states how many times a number is multiplied by itself, such as 3^2, or 3 "squared", meaning that the result is 3x3. With this in mind, look back at 4x4. Since the number multiplied is the same, we can write it using exponents. In this case, we are going to have 4^2, or four "squared". This is of course only one example, but I'm sure that that will likely be sufficient for your purposes.
How can you write 1 pound as a fraction?
yes..... if you are using it s a whole then its 1/1 and if ur using it as a part then its diffeent (exs. 1 to 2 is 1/2 and 1 to 14 is 1/14) get it?
