Question

which expression represents the largest number?
A. 6.1x10^-7
B.4.1x10^-7
C.3.1x10^-8
D.5.1x10^-8

Answer 1

the best answer is A.

Answer 2

Solutions:

As per the Question we have been asked to find the largest number from the given options.

The given options are

$A. 6.1*10^{-7}\\ \\ B.4.1*10^{-7}\\ \\ C.3.1*10^{-8}\\ \\ D.5.1*10^{-8}$

As we know smaller the number in exponent , smaller is the number.

Here we have $-8<-7$

So now we just need to see the option A and B, just choose the number in decimal with larger value.

Hence the correct option is $A \ 6.1*10^{-7}$
