Answer:

\frac{1}{72}

Step-by-step explanation:

Using the rule of exponents

a^{-m} ⇔ \frac{1}{a^{m} }, then

2^{-3} = \frac{1}{2^{3} } = \frac{1}{8} and

3^{-2} = \frac{1}{3^{2} } = \frac{1}{9}

Hence

2^{-3} × 3^{-2}

= \frac{1}{8} × \frac{1}{9}

= \frac{1(1)}{8(9)}

= \frac{1}{72}

Find the exact length of the third side
Daniel [21]

Answer:

√23

Step-by-step explanation:

When you are given two side lengths of a right triangle, you use the Pythagorean theorem to find the third side: a² + b² = c², where c is the hypotenuse (the longest side).

All you have to do is plug the given information in:

Remember, 13 is the hypotenuse for this triangle.

12² + b² = 13²

Simplify:

144 + b² = 169

Subtract 144 from both sides:

b² = 169-144

b² = 23

Square root both sides:

b = √23

And that's your answer!
