Which of the following is equivalent to 0.71 mL?

A.
0.00071 L

B.
0.0071 L

C.
71 L

D.
710 L

A

Step-by-step explanation: The answer is A because 0.00071 litres is the equivalent to 0.71 millilitres (I also used a calculator to proof check this). Also, 1000 mL is equivalent to 1 L meaning in simple form you would add an extra 3 zero's in fornt of 71 (0.71 --- 0.00071)

i believe the answer is letter c) 8

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
