-6+7=-6+6+1=10+1=1

thanks mathematician

$$\\27*(1/3)^{n-1}\\
=3^3* \;\;1/3^{n-1}\\
=3^3/3^{n-1}\\
=3^{3-(n-1)}\\
=3^{3-n+1}\\
=3^{4-n}\\$$

Your question doesn't make sense.

- pi/2 > -2

Multiply both sides by 2

-pi > -4

mult both sides by -1 but remember that if you mult or divide by a neg you must turn the inequality around

pi < 4

TRUE    pi is about 4.14

$$\\6m^4*8m^2\\
=6*8m^4m^2\\
=48\; mmmm \;mm\\
=48m^6$$

Try looking here for starters

just enter it exactly as you have written it.

Sorry I did the translation from Romanian to English but it did not make sense.

Ne pare rău, am făcut traducerea din limba romana în limba engleză, dar ea nu aveasens.

Yes - good work happy
