Can someone please help me with this I dont understand how to do it

The index is the superscript number outside the radical sign and the radicand is the numbers under the radical sign.

Step-by-step explanation:

For #1 the index would be 2 because it is a square root and the radicand would be the variable c.

For #3 the index would be 3 and the radicand would be t^3.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
