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
5p+2r=q
Move variable to the right
5p=q -2r
Divide both sides of the
equation by 5
q - 2
p =— — r
5 - 5
The final solution for
p is
q - 2
p =— — r, rER, qER
5 - 5
I cannot make the E like it should be made in mathematics on this keyboard. An elongated E.
