"2 to the power of 4" is written "two to the fourth power", and "8 to the power of 2" is known as "eight squared". And, eight squared is greater than two to the fourth power. Eight squared is 64, and two to the fourth power is 16.
9. Any negative number squared is positive.
That is 1/9x2
x squared times y to the negative four thirds power
Eight with a little eight above? 8* (Imagine the asterisk being an 8)
negative eight plus two times four to the second power
No difference. (-8)5 = (-85) = -85
Two to the eighth power (you add exponents to multiply).
The sum of all the natural numbers squared.
11 x 11
As an example, the product of (a + b) (a - b) is equal to a squared - b squared."Special product" simply means that there are special cases, when multiplying polynomials, that are worth memorizing. For example, if you know the above, then you can easily start factoring any expression that contains the difference of two perfect squares - for example, x squared minus 1, a to the power 6 minus b to the power 4, or even - if you start using complex numbers - a squared + b squared = a squared - (-1) b squared.
25 If you mean 5-1 the answer is .2 or 1/5
