X = 2
'x' is +4 or -4 .
The idea is to replace every "x" by "3", and then do the calculations.
No, because 8x8 is 64, not 16. The solution is 4 or -4.
That factors to 5(x - 4)(x + 4)(x2 + 16)
Yes, because: x+7 = 23 x = 23-7 x = 16
16 x 108 .
'x' is +4 or -4 .
The idea is to replace every "x" by "3", and then do the calculations.
That can be written as 2 x 2 x 2 x 2 and it equals 16.
33 x 24 = 27 x 16 = 432
= 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
16 to the 4th power, or 16 x 16 x 16 x 16 = 65,536
-24 = -2 x -2 x -2 x -2 = 16
No, because 8x8 is 64, not 16. The solution is 4 or -4.
-2 to the fourth power equals 16
(-2)^4 = (-2)x(-2)x(-2)x(-2) = 16
2 x 2 x 2 x 2 = 16
