Answer:
9
Step-by-step explanation:
2^28(3^-2/2^3)^4 x 1/(3^-5 x 2^8 x 6^0)^2
2^28(3^-2/2^3)^4 x 1/(3^-5 x 2^8 x 1)^2
2^28(3^-2/2^3)^4 x 243^2/256^2
2^28 x 1/2^12 x 3^8 x 243^2/256^2
243^2 x 1 x 2^28/256^2 x 3^8 x 2^12
2^28 x 243^2/2^12 x 3^8 x 256^2
2^16 x 243^2/3^8 x 256^2
2^16 x 3^10/2^16 x 3^8
=3^2
=9
Answer: 0.000527
Step-by-step explanation:
Given:
in standard form.
The standard form are also known as scientific notation.
Scientific notation is a way to write a very large or a very small number in the product of a decimal form of number [generally between 1 and 10] and powers of ten.
Since the power of 10 is negative, then it must be smaller than 1.
We can write the given number in decimal form as
![5.27\times\frac{1}{10^4}=\frac{5.27}{10000}=0.000527](https://tex.z-dn.net/?f=5.27%5Ctimes%5Cfrac%7B1%7D%7B10%5E4%7D%3D%5Cfrac%7B5.27%7D%7B10000%7D%3D0.000527)
Multiply 8 with pi since the equation for circumference is 2pi(r), or d(pi). The answer is 25.13
