Question

Надо правильно составить предложение : do teacher to the the experiment explained how to us .

Answer 1

The teacher explained to us how to do the experiment

Answer 2

It seems like you're trying to create a coherent sentence, but the structure is a bit unclear. If you're looking to express the idea that a teacher explained how to use an experiment, the correct sentence would be:

"The teacher explained to us how to use the experiment."

This sentence follows a more typical English word order. If you have any specific details you'd like to include or if you meant something else, please provide more context, and I'll be happy to help!
