Twenty one hundred thousandths.
10⁴ means 10 x 10 x 10 x 10 which equals 10,000. You can also call it "10 to the 4th" or "10 to the 4th power"
0.0284*10^4 0.0284*10000 284 2.84*10^2
To break it down: 1 x 10 = 10 10 to the power of 4 = (((10 x 10) x 10) x 10) 10 x 10 = 100 100 x 10 = 1,000 1,000 x 10 = 10,000 Answer: 10,000
1.0 x 10 to the power of 10 or 1.0 x 1010 can be written in standard form as 10,000,000,000 (10 billion).
Two specific cases of pairs of numbers whose product is 21 are: 1 x 21 and 3 x 7. The ratio of their sum to their difference is: 1 x 21 ... (21+1):(21 - 1) = 22:20 = 11 : 10, and 3 x 7 ... (3+7):(7-3) = 10:4 = 5 : 2. To find a general formula, let the larger number be x and the smaller be 21/x. Their sum is x + 21/x = (x^2 +21)/x Their difference is x - 21/x = (x^2 -21)/x Ratio of sum to difference is [(x^2+21)/x] / [(x^2-21)/x] = [(x^2+21)/x] * [x/(x^2-21)] = (x^2+21)/(x^2-21) Check: This formula produces the results found above.
3 x 10 to the 5th power + 3 x 10 to the 4th power + 2 x 10 to the 2nd power
1.835 x 10 to the negative 4th power in standard notation is 0.0001835
10⁴ means 10 x 10 x 10 x 10 which equals 10,000. You can also call it "10 to the 4th" or "10 to the 4th power"
3.14 x 10 to the negative 4th power in standard notation is: 0.000314

8.2 x 102 ÷ 6.3 x 104 ≈ 1.302 x 10-2
You add exponents, so it is 10 to the 4th power, which is 10000
