Answer:

6^{2}

Step-by-step explanation:

Use power rules.

\frac{6^{7} }{6^{5} }

6^{7-5}

6^{2}

Another way of solving in which the 6s on the numerator cancel with the 6s on the denominator:

\frac{6*6*6*6*6*6*6}{6*6*6*6*6}

\frac{6*6}{1}

6*6

6^{2}

Find the distance d (P1,P2) between the given points P1 and P2 P1= (5,4) P2=(-4,5)
oee [108]

Answer:

\sqrt{82  }

Step-by-step explanation:

d = \sqrt{(x_{1} - x_2)^2+(y_1-y_2)^2  }

d = \sqrt{(5 - (-4))^2+(4-5)^2  }

d = \sqrt{(9)^2+(-1)^2  }

d = \sqrt{81+1  } = \sqrt{82  }
