To subtract these two numbers, we need to subtract their coefficients and keep the same exponent:
(7.7790892759 - 1.077104669) x 10^8
Simplifying the coefficient:
6.7019846069 x 10^8
To subtract two numbers in scientific notation, we need to ensure that the exponents are the same.
Given:
7.7790892759 x 10^8
-1.077104669 x 10^8
To make the exponents the same, we can subtract the two numbers in front.
7.7790892759 - 1.077104669 = 6.7019846069
Now, we can use the exponent from the original numbers as the exponent in the final answer.
Therefore, the subtraction is:
6.7019846069 x 10^8
To subtract two numbers written in scientific notation, we need to make sure that both numbers have the same exponent.
Let's break down the given numbers:
7.7790892759 x 10^8
1.077104669 x 10^8
To make the exponents the same, we can compare the powers of 10:
10^8
Now, let's write the numbers in scientific notation with the same exponent:
7.7790892759 x 10^8
-1.077104669 x 10^8
Now, the exponents are the same, so we can subtract the numbers:
(7.7790892759 - 1.077104669) x 10^8
= 6.7019846061 x 10^8
Therefore, the difference between 7.7790892759 x 10^8 and 1.077104669 x 10^8 is 6.7019846061 x 10^8.
