Need help please with step by step

Recall some properites of exponentiation:

So for

(-2 x ² y ⁻¹) ⁻² (5 x ³ y) ²

first distribute the outermost exponents across each product:

((-2)⁻² (x ²)⁻² (y ⁻¹)⁻²) (5² (x ³)² y ²)

Simplify the powers using the multiplication property (the second one listed above) of exponents:

((-2)⁻² x ⁻⁴ y ²) (5² x ⁶ y ²)

Combine powers of the same terms using the addition property (the first one):

(-2)⁻² 5² x ⁻⁴⁺⁶ y ²⁺²

(-2)⁻² 5² x ² y ⁴

Finally, simplify the coefficient:

(-2)⁻² = 1 / (-2)² = 1/4

5² = 25

So you end up with

25/4 x ² y ⁴

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.

abde or 1,2,4, 5 is the answer
