The area of a square piece of land in square units can be represented by the expression 9q4r8s6. what is the length of one side of the piece of land?
3q2r6|s3| units
3q2r4|s3| units
18q8r16s12 units
81q8r16s12 units

Knowing that the area of a square is equivalent the square of its side length, the length of one side can be calculated by taking the square root of the area. The square root of the expression 9q^4r^8s^8 units is equivalent to 3q2r4|s3| units. When taking the square root of variables, the power they are raised to is divided by 2.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
