Write the exact value of the area of a square with a side length of √30 square units? *

Step-by-step explanation:

Information that we know about the square:

side length: which can asol be expressed as:

we can use this information to calculate the area by the formula for the area of a square:

we subtitute the side length:

the square root and the squared exponent cancel each other out (because they are opposite operations) and since this is an area it must have squared units:

The exact value of the area of the square is

answer: its the third option.

step-by-step explanation:

i just took the test.

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:
