Check my answer? what is the order of the numbers from least to greatest? a= 6.2x10^5, b= 1.1x10^-3, c= 4.3x10^-3, d= 5.2x10^-5 i think it's d, b,c, a (5.2x10^-5, 1.1x10^-3, 4.3x10^-3, 6.2x10^5)

Your ordering is correct.

When all numbers are positive and in standard form, the number with the least exponent will be the smallest. When the exponents are the same, the number with the smallest mantissa will be the smallest.

It’s hard to understand what you put.. can you show a picture ?
