2^-4 x 6^-4 = (2 x 6)^-4 = 12^-4 = (1/12)^4 = 1/20736 ≈ 0.000048225
2.0 × 10-3 written in standard form is 0.0020
2023 = 8.388608*1029 in standard form
2 090 000 in standard form: 2.09 x 10^6 ("2.09 times ten to the power of 6")
If you mean: 2^6 plus 4^2 = 80 and in standard form it is 8.0*10^1
212 = 4,096
20000
2.0 × 10-3 written in standard form is 0.0020
(2 x 5)2
20,000,000,000,000,000,000,000
The number is 400
5 to the fifth power is 25 (5 times 5 is 25)
2023 = 8.388608*1029 in standard form
(25) 6 x 42 = 3,072
The standard notation of 3.75 times 10 to the -2 power is: 0.0375
(2 x 5)2 = 100 2 x (5)2 = 50
25 = 32 in standard form.
If you mean 3.2147*10^-2 then it is equivalent to 0.032147
