Answer:

Step-by-step explanation:
An easy way to get exponents done if you're dealing with a multiple of 10, is to count the number of 0's present.
Since there are 3 0's in 1000, 10*10*10 = 1000 which just so happens to be the exponent needed
Answer:
The value of x = 3.5 or -4
Step-by-step explanation:
=> 2x² = 28 – x
=> 2x²+ x - 28 = 0
=> 2x² + 8x - 7x - 28 = 0
=> 2x ( x + 4 ) - 7 ( x + 4 ) = 0
=> (2x - 7 ) ( x + 4 )
=> x = 7/2 = 3.5 or x = -4
