(4.1 x 10-2) x (3.8 x 104) = (4.1 x 3.8) x 10-2+4 = 15.58 x 102 = 1,558
There is no need to estimate: 38 - 12 = 38 - (10 + 2) = 38 - 10 - 2 = 28 - 2 = 26.
86 ÷ 38 = 2 10/38 = 2 5/19 ≈ 2.263

38 + 44 = 82/2 = 41. So -3 Halfway between two numbers is half their sum: 1/2 x (-44 + 38) = 1/2 x (-6) = -3

According to my calculator, it is: 2^41 = 2.199023256×10¹²
There is no need to estimate: 38 - 12 = 38 - (10 + 2) = 38 - 10 - 2 = 28 - 2 = 26.

x^2 - x + 41 = these are for 5, 7, 10... after 40 they become composite with this equation 5^2 - 5 + 41 = 61 (Prime) 7^2 - 7 + 41 = 83 (Prime) 10^2 - 10 + 41 = 131 (Prime)
8.2 = 82/10.HCF(82, 10) = 2. Therefore, 82/10 simplifies to (82/2) / (10/2) = 41/2
10 - 41/2 = 51/2
86 ÷ 38 = 2 10/38 = 2 5/19 ≈ 2.263

38 + 44 = 82/2 = 41. So -3 Halfway between two numbers is half their sum: 1/2 x (-44 + 38) = 1/2 x (-6) = -3
Explanation: 41-2-2=37 ( 41-2=39)(39-2=37) 41 40 39 38 37 A simple way is: (41-40=39/39-38=37) This is because you take one every time. To make it simple you count backwards or to make it even simpler think it as counting from 1 to 2 but in reverse so that would make 2 to1. Because you take one/or count backwards each time but instead of taking 1 for your answer you just take 2 instead. DID YOU GET THAT
