multiply 2346 by 1400 than divide that by 73.33 Times 2.288 the answer is 2,0X10^4 need help with the process

2346*1400=3284400

73.33*2.288=167.77904

3284400/167.77904=19575.74677

writing it in the standard form 1.957574677*10^4

which is equivalent to 2.0*10^4

okay that kind of makes sense lets do another practice one.

(3.66X10^3)X(4.091X10^-5)

Jun 21st, 2015

multiply the real numbers 3.66 and 4.09; 3.66X4.09=14.9694

then 10^3X10^-5=10^(3-5)=10^(-2)

=14.9694*10^-2

=1.49694*10^-1

you can round off it to the nearest once=2.0X10^-1

or nearest tenth= 1.5*10^-1

okay my practice test rounded it to the tenth.  one question that i had was when you have this 10^3X10^-5=10^(3-5)=10^(-2) how do you end up with a exponent of -1

Jun 21st, 2015

note that the decimal point moved to the left by one step. therefore add one to -2 and get -1. Please check the decimal places

okay i see now there were a few problems like those thanks for your help. The next set is

366.6g/0.25L   X  1KG/1000G    X     1L/1000ML

Jun 21st, 2015

366.6/0.25 X 1kg/1000g X 1l/1000ml=1466.4 X 1kg/10^3g X 1l/10^3ml

=(1466.4*10^-3*10^-3)kg/ml. now write 1466.4 in standard form to get 1.4664*10^3

=((1.4664*10^3)*10^-3*10^-3)

=(1.4664*10^(3-3-3))

=(1.4664*10^(-3))

=1.4664*10^-3
