2 root 4 = 2 x 2; -2 to the power 4 is 16 (-2/4/-8/16)
= Z X and Y are examples. 2 to the power of X multiplied by 2 to the power 2 equals 16 What is X? X=2 2 to the power of 2 (2x2) multiplied (X) by 2 to the power of 2 (2x2) (2x2)4 X (2x2)4 = 4X4 = 16
x to the power of 2 is equal to x times x (x squared). This is written as x2.
x-2(x)+4/x^2 -4=x-2x+4/x^2 -4=-x-4+4/x^2
A similar question can be solved as below : If x to the power 4 plus 1 upon x to the power 4 equals 23 then what will be (x minus 1 upon x) to the power 2 equals what?a2 + b2 = (a + b)^2 - 2ab.so (x^2 )^2 + (1/x2)^2 = (x^2 + 1/x^2)^2 - 2 = 23.so (x^2 + 1/x^2) = 5.therefore(x - 1/x)^2 = (x^2 + 1/x^2) -2 = 5 -2 = 3.
30 x 22 = 1 x 4 = 4
-2 to the fourth power equals 16
x^2(x - 4)(x + 4)
4 x 2 means you are adding 4 two times, 4 x 2 = 4 + 4 = 8 4 ^ 2 (4 to the 2 power) means you are muliplying by 4 two times, 4 x 4 = 4 + 4 + 4 + 4 = 16
4 x 102 = 400
The GCF of 108 and 144 is 36, or 2^2 x 3^2
(4/7)^2 x (7)^4 = (4)^2 x (7)^2 = 16 x 49 = 784
Evaluate simply means work out. You times the first number by itself. The second number which is is small and beside the top corner of the first number decides how many times the first number gets times by itself. Here are 4 examples: 2 to the power of 4 = 2 x 2 x 2 x 2= 16 3 to the power of 3 = 3 x 3 x 3= 27 4 to the power of 3= 4 x 4 x 4= 64 5 to the power of 5 = 5 x 5 x 5 x 5 x 5= 3125
(10)3 x (2)2 = 1,000 x 4 = 4,000
8 x 9 x 5 and 4 x 3 x 25 360 and 300 The GCF is 60.
(4^5)x(4^-3)=(4^2)=16
2^-4 x 6^-4 = (2 x 6)^-4 = 12^-4 = (1/12)^4 = 1/20736 ≈ 0.000048225
