Work out the value of (6.8 x 10^2) x (1.3 x 10^-3) give your answer in standard form.

680*.0013=.884 because 6.8*10^2=680 and 1.3*10^-3=.0013 when you multiply them it'll give you .884

always move the decimal point the number of times that 10 is to the power to.

for example if its a negative number you move the decimal back and add zeros

if its a positive number move forward and add zeros

answer: give more info

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
