Create an abstract representation of mathematical solving and learning. The image should show a focused atmosphere with symbols to illustrate concepts of mathematics such as geometrical shapes, mathematical equations and symbols like cubes, pyramids, and spheres. Include illustrations of textbooks, pens, notepads to represent learning. Represent the complexity and vastness of mathematics by integrating a background of stars and galaxies.

i cant find the answers to Lesson 9: Exponents and Exponential Functions Unit Test

Algebra 1 B Unit 2: Exponents and Exponential Functions
I CANT FINDM if u do post a link

2,7,8,11 are wrong

Bro none of my question have these answers can somebody solve Unit 2 Lesson 9 Exponents and Exponential Function Unit Test?

Does anyone have the answers for this test. For 2017 because some of the questions are different?

Guys dont use @fhgwherbgh's answers i got a 50%
