Answer: last option.
Step-by-step explanation:
According to the Product of powers property, you have:

As you can see, when you can add the exponents when you have powers with equal base.
Then,
and
do not have the same base, therefore, the exponents can't be added.
Therefore, Eli is incorrect, because he added the exponents even though the bases are not the same.
5=5
17=(5•3)+2
53=(17•3)+2
161=(53•3)+2
485=(161•3)+2
1,457=(485•3)+2
Answer:

Step-by-step explanation:
To get the equivalent fractions, you simply have to multiply
the fraction with another fraction that would equal to 1.
2/8 x 2/2 (this is equal to 1) = 4/16; 1/4
3/8 x 2/2 = 6/16; 9/24
4/8 x 2/2 = 8/16; 1/2
Answer:
Isosceles triangles have two sides with the same length, and one side that ... Similarly, if two angles of a triangle have equal measure, then the sides ... (2) Set up an equation and solve for x. ... x = 60/2 x = 30. Each base angle of triangle ABC measures 30 degrees. ... In isosceles triangle RST, angle S is the vertex angle.
