3.9 times 10 to the seventh power

Hey there!

3.9 times 10 to the seventh power is equivalent to the equation 3.9 ×

The seventh power indicates the amount of times the decimal moves to the right of 3.9, so that expression would be equivalent to 39,000,000.

Hope this helps!

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
