<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.

Answer:
I = 2,340
Step-by-step explanation:
The formula for interest is
I = P × R × T / 100
P = $5200
R = 15%
T= 36 months; T is meant to be in years so we will convert it from months to years
1 year = 12 months
So 36 months
= 36 /12 = 3 years
I = (5200 × 15 × 3)/100
I = 234,000 / 100
I = 2,340
