Explain what is important about the sign of the exponent and why it changes the solution.

An exponent changes the whole number overall. Exponents have a big effect on the solution because it intensely multiplied the number by itself multiple times. For example, 726165 to the zero power would equal 1. That is a huge change and would change the overall solution. Multiplying the number by itself caused a huge change, changing the way the exponent would be too. negatives in an exponent are also important too, easily changing the solution quickly.

Step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

pls mark as brainliest

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
