The letter i in mathematics represents √-1. So, keep in mind. i = √-1.
Let's factor √-32 with the i in mind.
√-32 = √(32 * -1) = √32 * √-1 = √32i.
Just remember this formula: √-x = i√x
Answer: 1. 10
2. an = an - 1 + 7 where a1 = -10
Step-by-step explanation:
90 + 2x + 104= 360,
360-194 = 2x
166 = 2x, x =83.
X+67 = 150, X+37= 120.
-> 150, 120
The correct option is 6 X 4.
To arrange in descending order means that you will write the largest value first followed by the other smaller ones. From the question given above, we have the following values:
3x3 = 9
6 x 4 = 24
-2 x 2 = -4 and we have -7x.
Thus, the largest value is 6 x 4.
Answer:
Simplified = 64.
Step-by-step explanation:
81-8 & 5 + 4 = 73-9 = 64.
