Given:
Standard form and expanded notation
Find-:
The number shown in standard form and expanded notation
Explanation-:
The standard form is
Standard form = The standard form is
For example, is
The expanded form is
The expanded = Expanded form is a way to write a number by adding the value of its digits. We can use a place value chart to determine the value of a number's digits.
For example
Answer:30 divided by 4 equals 7.5
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
For the divisor on the left of the division symbol, the -3 symbolizes that the -3 is a root. This means that when we plug -3 into our divisor, the answer is 0. Therefore, as x+3=0 when x=-3, the divisor is x+3.
Next, for the dividend, we can start on the left with no x multiplied to it and then add one degree of x for each value to the left. This results in
6 + -4 * x¹ + 4 * x² + 2 *x³
= 2x³ +4x² -4x+6
Answer:
sqrt(21)
Step-by-step explanation:
x = sqrt(7*3) = sqrt(21)
