The answer is D. 77. This stuff is 2EZ for me
When you multiply two numbers in exponential notation whose bases are the same, you just keep the base the same and add the exponents.
In this case, you have (2^6) * (2^6) = 2^(6 + 6) = 2^12.
We can change the base of 4^6 into 2:
(2^2)^6
Is this the same as 2^12? Well, when we have an expression like that above, we multiply the exponents together, so we get: (2^2)^6 = 2^12.
Therefore, Nicholas is correct.
Assuming your first equation is y = 5x+9, the equations describe lines that are coincident.
_____
Multiplying the second equation by -1, it becomes y = 5x+9, the same as the first equation.
C and b , both can be a number multiplied by 10 to the power of -6
