The surface area of the Sun is about 4x3.141x(7x10^5)^2 square kilometers. Simplify the expression
What did you get?
To simplify the expression, let's start by simplifying the powers of 10:
(7x10^5)^2 = 7^2 x (10^5)^2 = 7^2 x 10^(5x2) = 49 x 10^10
Now, substituting this into the original expression:
4 x 3.141 x (7x10^5)^2 = 4 x 3.141 x 49 x 10^10
Multiplying the numbers together:
4 x 3.141 x 49 = 615.744
So, the simplified expression is 615.744 x 10^10 square kilometers.
To simplify the expression, we start by evaluating the exponents and performing arithmetic operations in the correct order.
The expression given is 4 x 3.141 x (7 x 10^5)^2.
First, let's calculate the term (7 x 10^5)^2. To find the result, we need to multiply 7 by itself and then multiply the result by 10 raised to the power of 5.
7 x 7 = 49
10^5 = 100,000
Therefore, (7 x 10^5)^2 = 49 x 100,000 = 4,900,000.
Now, we can substitute this value back into the original expression:
4 x 3.141 x 4,900,000.
Next, we can multiply the remaining terms together:
4 x 3.141 x 4,900,000 = 61,681,600.
So, the simplified expression is 61,681,600 square kilometers.
4*3.141*(7*10^5)^2 = 12.564*49*10^10 = 615.636*10^10 = 6.15636*10^12.
