Lab 1.1 Reviews

1.) Write out the powers starting from 20 to 26. Next place the values of the powers below. In each block below enter a one subtract that value from the number 127 until you have nothing remaining and all values equal 127.

2.) The values 102 and 00102 are equal because the zero are not equal to anything in the beginning of the equation.

3.) The first four digits in the base 5 would be 1,5,25,125

4.) It would be more difficult because you would be doing more than adding the values together to equal your decimal number it would include multiplying and a more complicated formula.
