Which is equal to 5 exponent of -4

= = 0.0016

Step-by-step explanation:

I'm assuming you mean (which could also be written as 5^-4, for future reference).

Negative exponents actually mean you'd use the term in the denominator, taking away the negative portion. It's difficult to explain in words, and is easier to see.

=

Notice how the -4 changes to 4, and it becomes the denominator.

is also 625, so is also 1/625, or the decimal version (0.0016).

I hope this helps!

step-by-step explanation:

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.
