Answer:
Step-by-step explanation:
When we have a number to a fraction power, we need to note that
- It's the same as taking the denominator root of the base to the numerator power
Basically, for example, 
is the same as 
since the numerator is 1 (
) and the denominator is 2 ().
Applying this same logic to 
-

Answer:
$32,000
Step-by-step explanation:
Yearly investment = $3,000
Number of years = 20
Investments earned an average of 8 percent a year.
Total invested amount = $3,000 × 20 = $60,000
Current value of investment = $92,000.
We need to find the total earnings on the investment.
Earnings = Current value of investment - Total invested amount
Earnings = $92,000 - $60,000
Earnings = $32,000
Therefore, the total earnings is $32,000.
Answer:
Here is the rule: when a and b are not negative
√(ab) = √a × √b
Example: simplify √8
√8 = √(4×2) = √4 × √2 = 2√2
(Because the square root of 4 is 2)
In other words 2 x 4 = 8 = √2 x 4 but 4 can be simplified more (2 x 2) so 2 (previous 4) moves to the left of the square root leaving 2√2
To simplify a square root: make the number inside the square root as small as possible (but still a whole number)
or you can use a simplifying square root calculator.
Step-by-step explanation:
let gold fish= X
let Plecos fish= Y
X +Y = 17................(I)
13.49X + 3.25Y =198.61........(II)
solve simuteniously to get
X = 14
Y = 3.....therefore
she bought 14 gold fish and 3 plecos fish
