The expression "1".
You could try 67*1
17*9 = 17*(10-1) = 17*10 - 17*1 = 170 - 17People who do not know the 17 times table might find the equivalent version easier to evaluate.
The expression 1000^(1/3) is equivalent.
5(y + 1)
1/25
5d-1=-11 5d=-11 + 1 5d=-10 d= -10/5 d=-2
15 1/2
The expression "1".
Do you mean: 11d +1 = 5d+49? If so: 11d+1 = 5d+49 11d-5d = 49-1 6d = 48 d = 8
-30/1
15 1/2
0.0156
2m + 1
You could try 67*1
17*9 = 17*(10-1) = 17*10 - 17*1 = 170 - 17People who do not know the 17 times table might find the equivalent version easier to evaluate.
Re-write it with a root. If the power of the expression is less than 1, for example x1/3, the expression could be rewritten as cube root of x.
