To find the how many times greater is the storage capacity of a 1-gigabyte flash drive than a 1-megabyte flash drive we have to apply exponent operation.
The storage capacity of a 1-gigabyte is 1000 greater than 1-megabyte flash drive.
Given:
The given exponent for gigabyte is,
The given exponent of megabyte is,
- The power rule of exponent rule is defined as if raise the a number with exponent to power then we will mulitply exponent to the power times.
- to change the negative exponent into a positive we have to invert the base.
Calculate the storage capacity.
Thus, the storage capacity of a 1-gigabyte is 1000 greater than 1-megabyte flash drive.

Step-by-step explanation:
Given
2x² + x - 1 = 2 ( subtract 2 from both sides )
2x² + x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 3 = - 6 and sum = + 1
The factors are - 2 and + 3
Use these factors to split the x- term
2x² - 2x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x + 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -
