Answer: d. 512
Step-by-step explanation:
You need to remember that:
Then, given the equation:
You can find the value of "n" that make the equation true, by solving for "n".
So, to solve for "n", you need to raise both side of the equation to power 3. Therefore, you get:
Then, the value of "n" that makes the equation true is: 512 (You can observe that this matches with the option d).
Answer:
2
Step-by-step explanation:
we start simplifying by removing the parenthesis
Multiply the exponents inside the the parenthesis
3^4 * 2^4
Now we apply exponential property
a^m * a^n = a^ (m+n)
3^4 * 3^-3 = 3^ (4-3) = 3^1
3 or 3^1 are same
3^1 at the top and bottom so we cancel it out
\frac{2^4}{2^3}
we apply log property . a^m / a^n = a^m-n
Now subtract the exponents
2^(4-3) = 2^1 = 2
Answer:
About 145.27
Step-by-step explanation:
The diameter of a circle is twice the radius, meaning that the radius of this circle is 13.6/2=6.8.
Hope this helps!
