1495/1000 as the decimal point is after three places

=1.495

Answer 2

Answer:

0.598

Step-by-step explanation:

here we can take 0.023 as 23*10^-3 [10 to the power -3]

it will becames as = 23*10^-3 *65

                              =23 * 5^-3 *2^-3*5*13 [i have expanded the 10^-3 and 65]

                              =23 *5^-2*2^-3*13 [i.e. the exponent rule that the exponents        of same bases can add when are in multiplication]

                       =23*5^-2*2^-3*13

                      =  299*10^-2 *2^-1

[here i splited the term 2^-3 to 2^-2 and 2^-1]{also i multiplied 5^-2 and 2^-2 into 10^-2 just like we splitted 10^-3  into 5^-3 and 2^-2}

                  =0.598
