The solution for x is 3. Since 3 is to 10 as 2x is to 20 Then the ratio holds: 3 / 10 = 2x / 20 Solving for x: 3 / 10 = 2x / 20 0.3 = x/10 (0.3 * 10) = x 3 = x x = 3
3 x 10 to the 5th power + 3 x 10 to the 4th power + 2 x 10 to the 2nd power
(5)21 x (4)11 = (5)11 x (5)10 x (4)11 = (5)10 x (5 x 4)11 = (5)10 x (20)11 =(5)10 x 20 x (20)10 = 20 x (5 x 20)10 = 20 x (100)10 = 2 x (10)1 x (10)20 =2 x (10)21 = 2,000,000,000,000,000,000,000
1000 = 1X 10(to the power of 3) 500 = 5 x 10(to the power of 2) 30 = 3 x 10(to the power of 1) 3 = 3 x 10(to the power of 0)
|x-3|/2=10 |x-3|=20 |a|=b means a=b or a=-b Then : x-3=20 or x-3=-20 So: x=23 or x=-17
The value of 4.2 X 10 to -3 power is 0.0042
20/30 = (2 x 10)/(3 x 10) = 2/3
it would be 20 x 10 + 20 x sqrt 3 (1.732) 200 + 34.6 = 234.6
20 billion can be written as 2 x 10^10.
Three to the tenth power is the same as multiplying three by itself 10 times: 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 = 59,049
2 x 10^1
2 x 10^1 x 1 x 10^5 = 2 x 10^6
