What happens to exponents when they are being multiplied? (ex: 5^14 x 5^6 = ?)

The exponents are added together to create a simplified powers equation. There for the example would be equivalent to 5^20.

Besides apologizing for the issue at hand, get your supervisor or manager. They should have both the customer's and your back. They are also able to navigate a situation, and potentially alleviate the situation at hand.

Describe a general lesson that incorporates 1-D, 2-D, and 3-D tiers of learning. Please include examples for all.

When teaching with a 1-D strategy, it is primarily written words or numerals on a white/chalk board. For example, when teaching vocabulary, the teacher can write out each word and the definition to fulfill this strategy (i.e. apple- a seeded round fruit that grows on a tree, with a stem, and comes in different colors). To make this vocabulary lesson 2-D, the teacher can draw an apple or have a picture of an apple printed out. This strategy allows for the learner to associate the word with an image/object. Finally, to make this lesson 3-D, an actual apple can be brought out. This lesson might even benefit from going in reverse order. To elaborate, the teacher will start by placing the apple on the table (2-D or 3-D) and having the students describe it, from there the teacher can ask the students to use their observations and/or their past knowledge to create a definition of an apple, which can then be written on the board.
