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 ^?
Several ways :- 161 42 24
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
16
A base raised to a negative power is equal to 1 divided by that base raised to a positive exponent. So 16 raised to (-3/2) is equal to 1/ (16 raised 3/2), or 1/64.
Multiplying a number by its self is called squaring a number When using exponents, the second power of a whole number is called a perfect square too, For example, write 4 squared = 16, 7 squared = 49, and 265 = 70, 225 are all perfect squares.
24 = 16
It is: 2^4 = 16

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
to me i think 2 to the power of 2x2 to the power of 2 * * * * * 16 = 24
No, but you can rewrite it as an expression with exponents if you want.

Using a 16-letter alphabet.
2^4
First you need to solve for y. So write 4x2+y=16 so y=16-4x2 Now write f(x)=16-4x2
