Question

(5.4*10^2)-(1.3*10^4)
answer in a*b form

Answer 1

-1.24*10^4

Explanation:

Firstly observe the Digit term of the given operation under scientific notation. and now we are left with the 10th exponents which involves the basics of 10^a - 10^b = 10^a/b and so according to this rule...we have 10^2/10^4 which results in 10^-2

and thus we have −12460 = -1.24*10^4
