Answer: 1
Step-by-step explanation: Whenever you take the power of a power, the find the answer you can multiply the two exponents, for example:
(x^3)^4 = x^12
We will use that here.
a^8a^6 = a^14
((a^14)^1/7) = (a^2)/a^2
Our answer is 1
Answer:
His gain percent is 20%
Step-by-step explanation:
In this question, we want to find the percentage gain of the business.
We need the following parameters;
The cost price which is the sum of the amount she bought the goods + the amount spent on transport
Using the values we have in the question;
The cost price will be;
13,600 + 400 = Rs 14,000
The selling price = Rs 16,800
Mathematically the percentage gain will be;
% gain = (selling price- cost price)/selling price * 100%
% gain = (16,800-14,000)/14,000 * 100/1
% gain = 2800/14,000 * 100/1 = 1/5 * 100/1 = 20%
The equation of a circle is (x-h)²+(y-k)²=r², with h being the x value in the center, k being the y value, and r being the radius. x and y can stay variables, so we can plug numbers in to get (x-0)²+(y-3)²=5²=25=x²+(y-3)²
Answer:
B
Step-by-step explanation:
1. Given mathematical statement
So,
2. Rewrite it as
So,
3. Combine like terms 
and 
So,
4. Add to both sides:
So,
5. Subtract 3 from both sides:
So,
6. Divide both sides by 5:
So,
