Recognize that "( ) over 2^3" means ( ) • 2^-3. Use the rule of exponents
.. (a^b)^c = a^(b•c)
= 2^-16•5^10•19^-2 • 5^-8*2^-12 • 2^28
Now, you can use the rule of exponents
.. (a^b)*(a^c) = a^(b+c)
= 2^(-16 -12 +28) • 5^(10 -8) • 19^-2
= 5^2 • 19^-2
= 5^2 / 19^2
= 25/361
Answer:
4² =16
5² =25
Step-by-step explanation:
Take the perfect squares and determine if 17 is closer to the 2 square roots it is in-between. In this case, 17 is closest to 16.
Answer:

Step-by-step explanation:
Answer:
m3 is 60 degrees
Step-by-step explanation:
Angles 1 & 3 are complementary angles. What that means is that the two angles equal 180 degrees. We already have 120 degrees with m1, so subtract that from 180 for 60 degrees.
