What is 1/64 to the second power as a negative exponent? help please!
masya89 [10]
8^2 = 64 since 8*8 = 64
Squaring a number is the same as multiplying it by itself. 

Since 8^2 = 64, this means
1/64 = 1/(8^2) = 8^(-2)

So, 1/64 = 8^(-2)
where the exponent is negative 2

Solve both questions please ❤️❤️

Answer:

1. y=7.2

2. x=18

Step-by-step explanation:

1. Triangles CMN and CBA are similar triangles (by AAA postulate). Similar triangles have proportional corresponding sides, so

\dfrac{CM}{CB}=\dfrac{CN}{CA}\\ \\\dfrac{12}{12+y}=\dfrac{10}{10+6}\\ \\12\cdot 16=10\cdot (12+y)\\ \\192=120+10y\\ \\10y=72\\ \\y=7.2

2. GK is angle G bisector. Use angle bisector's property:

\dfrac{GH}{GI}=\dfrac{KH}{KI}\\ \\\dfrac{40}{24}=\dfrac{30}{x}\\ \\40x=24\cdot 30\\ \\4x=24\cdot 3\\ \\x=6\cdot 3=18
