Answer: -60a^6
Step-by-step explanation:
multiply 10 and 6. combine the exponents
In one <span>shipment there are 98 balls, each costs $2, then the total price of these 98 balls is

.
</span>
<span>The total cost of playground balls in three shipments is:
</span><span>
</span><span>

.</span>
To write the following as a fraction, we will;
First write the decimal over 1
That is;

Then multiply the numerator and the denominator by 100


Now, go ahead and reduce the fraction

Working on x and y first, we get:
<span><span><span>x6 / </span><span>x3</span></span>= <span>x3</span></span> and
<span><span><span>y6/ </span><span>y12 </span></span>= 1/ <span>y6</span></span> so, we have:<span><span> 2 <span>x3 / </span></span><span>y6
Entering values in original equation, we get:
</span></span><span>(2 <span>x3/ </span><span>y6</span><span>)^2</span></span>=4 x^6 / y^12
