Solving 5^5.5^{-12} we get \frac{1}{78125}

Step-by-step explanation:

We need to solve: 5^5.5^{-12}

It can be solved using the exponent rule. If bases are same, then the exponents are added. i.e a^m.a^n=a^{m+n}

Applying exponent rule:

5^5.5^{-12}\\=5^{5-12}\\=5^{-7}\\

Another exponent rule says: a^{-1} =\frac{1}{a}

So,

5^{-7}\\=\frac{1}{5^7}\\=\frac{1}{78125}

So, solving 5^5.5^{-12} we get \frac{1}{78125}

kotegsom [21]
  • Answer:

<em>A. x ≤ - 9 or x ≥ 9</em>

  • Step-by-step explanation:

<em>x² ≥ 81</em>

<em>| x | ≥ 9</em>

<em>x ≥ 0 => x ≥ 9 => x ∈ [ 9 ; + oo)</em>

<em>x < 0 => x ≤ - 9 => x ∈ ( -oo ; - 9 ]</em>

<em>x ∈  ( -oo ; - 9 ] ∪ [ 9 ; + oo)</em>

Can someone check this for me please? Thank you!
sineoko [7]

Step-by-step explanation:

You've got the concept correct, but be careful with your parentheses.  You should write it 3/(2n).  Otherwise it looks like three halves n.

What is the length of the hypotenuse for a right triangle with legs of length 9 and 40?​
Step2247 [10]

Answer:

c = 41

Step-by-step explanation:

{c}^{2}  =  \sqrt{ {a}^{2} +  {b}^{2}  }

c =  \sqrt{ {a}^{2} +  {b}^{2}  }

c =  \sqrt{ {9}^{2} +  {40}^{2}  }

c =  \sqrt{81 + 1600}

c =  \sqrt{1681}

c = 41
