Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form as: 1,268
Well, you simply say that in the 4-digit number, there are 4 spots for numbers. In each spot, you can use each number, so there are five possibilities of numbers for each slot. You could list them (1246, 1248, 1264, 1268, etc.) but there is a much easier way. You say that in each spot you can have five different instances of a number.5 5 5 5_ _ _ _Therefore, you can multiply 5 by 5 by 5 by 5 (5^4 or 54) to get (5*5)=25. 25*5=125. 125*5=625. 625*5=3125. So, there are 3125 ways to create a four-digit number from the digits 1, 2, 4, 6,8, if they can repeat.=======================================Another contributor dissented:Vorksholk was on exactly the right track, but got carried away and multiplied once too often.54 = (5 x 5 x 5 x 5) = 625
