Answer:
Step-by-step explanation:
discriminant=5²-4×1×7=25-28=-3<0
no real number solution.
No because a mixed number is a whole number with a fraction and the smallest whole number is one so 1 and a fraction pulse and a fraction will equal more than 2
Answer:
Exponents
Step-by-step explanation:
exponents are basic short cut to write numbers like 100, 1000, 10000, 1000000 and so on.
Exponents can also be defined as 10 raised to a power x whether positive or negative

They are mostly used in expressing units in standard form.
<h3>examples of basic positive exponents</h3>




basically the power represent the the number of zeroes after the 1.
<h3>examples of basic negative exponents</h3>




in negative exponents the power represents the number of zeroes before the 1. including the 0 behind the decimal point.
this is the basic lay down of how exponent work but one more quick example for maximum understanding
<h3>quick example</h3>




hope you grasp the concept involved in multiplication with other terms.
