Question

A light on a computer comes on for 26,700 microseconds. One microsecond is 10^-6 seconds. Work out the length of time, in seconds, that the light is on (a) in standard form and (b) as a decimal.

Answer 1

1 microsecond = 10^-6 seconds
26700 microseconds = 26700* 10^-6 seconds

Answer 2

Does it help?

Answer 3

Yes, thanks again! :)

Answer 4

Did u convert it into standard form and decimal?

Answer 5

Yes. :)

Answer 6

GREAT

Answer 7

If one microsecond is equal to \[10^{-6}\]
then, 26700 microseconds are equal to:
\[26700 \times 10^{-6} \]
and 26700 can also be written as:
\[2.67 \times 10^{4}\]
so your whole equation would be:
\[2.67 \times 10^{4} \times 10^{-6}\]
which according to the exponential rules is:
\[2.67 \times 10^{4-6}\]
which is:
\[2.67 \times 10^{-2}\]
which in decimal form is:\[0.0267\]
