<span>Solution:
7-6 +i+2i = 1+3i</span>
Step-by-step explanation:
24 ÷ 3:4
= 24 / 3 / 4
Basics
a / b / c = a / b / c / 1
....1 is normally invisible since a number
divided by 1 is itself. i wrote 1 down to show the reciprocal property.
a/b/c/1 = a/b × 1/c = a/bc ...Flip the number you're dividing with.
24/3/4 = 1/24 × 3/4 = 3 / 96 = 3 × 1 / 3 × 32 ...cancel the 3s'
= 1 / 32.
Answer:
I think the answer is D
Step-by-step explanation:
Answer:
The smallest power of 10 that will exceed 
is 
.
Step-by-step explanation:
We can use the following approach to determine the smallest power of 10 that will exceed M. We can transform that number into scientific notation, which is of the form:
, 
Where:
- Integer part, formed by a digit, which is of the highest order.
- Decimal part, formed by a digit onwards.
- Power grade.
The smallest power of 10 that will exceed M is 
If 
, then, the power grade is number of spaces that dot must be moved leftwards. In this case, dot must be moved 5 spaces on the left. The integer part is 1 and the decimal part is 1852665902. Then, the value of in scientific notation is:
Then, the smallest power of 10 that will exceed is .
Answer:
x = ± sqrt(43)
Step-by-step explanation:
2x^2 - 28 = x^2 + 15
Subtract x^2 from each side
2x^2-x^2 - 28 = x^2-x^2 + 15
x^2 -28 = 15
Add 28 to each side
x^2 - 28 +28= 15+28
x^2 = 43
Take the square root of each side
sqrt(x^2) = ± sqrt(43)
x = ± sqrt(43)
