Find two positive numbers whose difference is 8 and whose product is 1505.
1 answer:
Answer:
The two positive numbers are 35 and 43.
Step-by-step explanation:
Let the two positive numbers be x and x + 8.
It is given that their product is 1505.
Therefore, x(x + 8) = 1505
x(x + 43) - 35(x + 43) = 0
(x + 43)(x - 35) = 0
x = -43, x = 35
Since, the numbers are positive, x = 35 is only valid.
The other number is x + 8 = 35 + 8 = 43.
Hence, the required positive numbers are 35 and 43.

<h3>What are Scientific notations?</h3>The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.
For example, 6,500,000,000,000 can be written as 6.5×10¹².
As the value of the scientific notation is given 2.4x10⁻⁴, therefore, for bringing it in the standard form we need to shift the decimal to the left by four digits. So,
Hence, the value of the number 2.4x10⁻⁴ in the standard notation is 0.00024.
