Answer:

Below in bold.

Step-by-step explanation:

c) 3 x (9^2)^3/4 x ((81^3)^5/6

= 3 x 81^3/4 x 81^15/6

= 3 x 81^(3/4 + 15/6)

= 3 x 81^13/4

= 3 x 3^13

= 3^14

= 4,782,969.

f) (5x^-1y^2)^-2 / (25 x^2 y - 1)^2

=  5^-2 x^2y^-4 / 625 x^4y^-2

=  5^-2 x^-2 y^-2 / 5^4

= 5^-6 x^-2y^-2

= 0.000064x^-2y^-2.

You just bought a new laptop and paid an initial payment of $150.00. You will make 12 payments of $69.50. How much will the comp
kicyunya [14]

The computer will cost $924.96 after 6% tax.

<h3>Total cost of laptop</h3>

The initial payment of the laptop made = $150.00

The remaining balance that would be made = 12 × 69.50

=$834

Therefore total cost of laptop before tax = 834 + 150

= $984

But tax is 6% of total cost =

\frac{6}{100}  \times 984

\frac{5904}{100}

= $59.04

Therefore, total cost of laptop after tax = 984 - 59.04

= $924.96
