Okay. First thngs first, let's divide each of them. 2.6/1.3 is 2. Now in terms of exponents, we would just simply subtract the powers, because we are doing division. 9 - 2 is 7. The value of the expression is 2 * 10^7. Even writing the problem out in number form (2,600,000,000/130), you can still see the answer to the problem as 20 million. The answer is B.
The answer is the a next to the 5
3x^2 - 8= 40
add 8 to both sides
3x^2= 48
divide both sides by 3
x^2= 16
take the square root of x and 16
x= 4
ANSWER: x=4
Hope this helps! :)
