Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2).  Write a formula for y in terms of x.

The tens digit is 2 more than the units digit.  Using the letters x and y, write out the proper equation.

Now solve your two equations simultaneously for x and y.

Use the power property to rewrite log3x9.
Kitty [74]

Answer:

\log _3\left(x^9\right)=9\log _3\left(x\right)

Step-by-step explanation:

Given the expression

\log _3\:x^9

now rewriting the expression

\log _3\:x^9

\mathrm{Apply\:log\:rule\:}\log _a\left(x^b\right)=b\cdot \log _a\left(x\right),\:\quad \mathrm{\:assuming\:}x\:\ge \:0

=9\log _3\left(x\right)

Therefore,

\log _3\left(x^9\right)=9\log _3\left(x\right)

Does anyone know how to do this?
sineoko [7]

Answer:

\boxed{\tt x=\sqrt{85} }

Step-by-step explanation:

When making a right triangle with 2 points, the distance is the hypotenuse which can be represent as "x"

To find the distance we can use the Pythagorean theorem.

\boxed{{\tt a^2+b^2=c^2}}

→ \tt a=9

→ \tt b=2

→ \tt c=x

<u>Let's Plug in the side lengths:</u>

  • \tt 9^2+2^2=x^2

<u>Evaluate 9²= </u><u>81</u><u> and 2²= </u><u>4</u><u>:</u>

  • \tt 81+4=x^2

<u>Now, add 81+4= 85</u>

  • \tt 85=x^2

<u>Take the square root of both sides:</u>

  • \tt x=\sqrt{85}
