Please help me with 8, 9, and 10 thanks! Show work too

Harrizon [31]

In 8, 9, 10, all the triangles are similar, meaning corresponding sides have the same ratio.

8. hypotenuse / (short side) = 25/x = x/9
x² = 25*9 = 5²×3²
x = √(5²×3²) = 5*3 = 15

9. (long side) / (short side) = x/7 = 9/x
x² = 7*9
x = √(9*7) = 3√7

10. (short side) / (long side) = x/48 = 48/64
x = 48²/64 = 36

Answer:

2

Step-by-step explanation:

${16}^{ \frac{1}{4} } \: can \: also \: be \: written \: as \: ( {{2}^{4})}^{ \frac{1}{4} }$

because ${2}^{4} = 16$

So,

${( {2}^{4} )}^{ \frac{1}{4} } = {(2)}^{4 \times \frac{1}{4} } = 2$
