Question

Can someone help me on this a and b

Answer 1

For b the answer is 2.726x10^-2

So u move the decimal between the first and second number. And then for the exponent of 10, it’s -2 because to get from ur answer number (2.726) to the original number (0.02726) you’ll have to divide by 100 (=10^2). And dividing by 10^2 = x10^-2 (basically when u divide by 10^n = x10^-n)
Therefore the answer is 2.736x10^-2

Hope u understand what I’m saying, sorry if my explanation doesn’t rlly make sense

Answer 2

Answer:

i only know a sorry I dont know b a is 4.249×10^7

Step-by-step explanation:

you put the decimal in between the first two numbers so 4.249 then multiply as many powers of ten until you get your answer which is 4.249×10^7 hope this helps
