Answer:

= a⁸/b⁻¹⁰

Step-by-step explanation:

Simplify the expression

(a^2b^-3/a^-2b^2)^2

= a⁴b⁻⁶/a⁻⁴b⁴

Using the law of indices

= a⁴⁻⁽⁻⁴⁾/b⁻⁶⁻⁴

= a⁴⁺⁴/b⁻¹⁰

Answer:

Blue: 13/100 = 0.13 = 13%

Purple: 130/100=1.3=130%

Step-by-step explanation:

The picture shows 100 cubes in a grid that's 10 by 10. This means the shaded amount is a number out of 100. The first is 13 out of 100 which converts to 0.13 and 13%. The second has all the cubes shaded which means 100/100 which is 1 or 100% plus the last has 30 cubes out of 100 which converts to 0.30 or 30%. Together this makes 130/100 or 1.30 or 130%.
