Answer:
3 * 10^4
Step-by-step explanation:
Here, we want to make a division
We want to divide 9 * 10^2 by 3 * 10^-2
That would be;
(9 * 10^2)/(3 * 10^-2)
= 9/3 * 10^2-(-2)
= 3 * 10^4
Huh? 5x100 = 500. Is that the question
Answer:
7.7 is the answer
Step-by-step explanation:
(credit to manics.info)
Step 1:
Calculate the square root of 60 to be:
√60 = 7.74596669241483
Step 2:
Reduce the tail of the answer above to two numbers after the decimal point:
7.74
Step 3:
Round 7.74 so you only have one digit after the decimal point to get the answer:
7.7
To check that the answer is correct, use your calculator to confirm that 7.72 is about 60.
Hope this help and have a great day!
Answer:
-6i
Step-by-step explanation:
Complex roots always come in pairs, and those pairs are made up of a positive and a negative version. If 6i is a root, then its negative value, -6i, is also a root.
If you want to know the reasoning, it's along these lines: to even get a complex/imaginary root, we take the square root of a negative value. When you take the square root of any value, your answer is always "plus or minus" whatever the value is. The same thing holds for complex roots. In this case, the polynomial function likely factored to f(x) = (x+8)(x-1)(x^2+36). To solve that equation, you set every factor equal to zero and solve for the x's.
x + 8 = 0
x = -8
x - 1 = 0
x = 1
x^2 + 36 = 0
x^2 = -36 ... take the square root of both sides to get x alone
x = √-36 ... square root of an imaginary number produces the usual square root and an "i"
x = ±6i
