2x = 1,000,000
You need to use logarithms to find x.
logab = c if ac = b.
With that in mind, you can change this equation into:
log2(1,000,000) = x
If you enter this into a calculator, you will get approximately 19.93.
2 to the power of 19.93 is 998,913, which is close to one million, so this is a legitimate answer.
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.
= 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
No, to be linear, both the power of x and y need to be 1. Since x is squared, the power of x is 2.
if y = 2x then x = log2 y
logx^2=2 2logx=2 logx=1 10^1=x x=10
1000 x 1000
1000000
1,000 x 1,000 = 1,000,000
34x = 1000000 Therefore x = 1000000/34 Rounded to two decimal places, x = 29411.76
20 percent of 1000000 dollars is 20/100 x 1000000 which equals 20000
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.
It equals 0. * * * * * Unless the question is (-x)2 + (+x)2. In that case, the answer is 2x2
X = 2

22.807354922 or log7(2)

That can be written as 2 x 2 x 2 x 2 and it equals 16.
