Count the number of times each digit appears in the multiplication and then write each digit once in the multiplication with the number of times they originally appeared as an index (little superscript number):
3 appears 2 times
5 appears 4 times
7 appears 1 times
→ 3 x 3 x 5 x 5 x 5 x 5 x 7 = 32 x 54 x 71
However, when the index is 1, it is not normally written, so this becomes:
3 x 3 x 5 x 5 x 5 x 5 x 7 = 32 x 54 x 7
If x = -7 and y = -3 then 5(-7) -2(-3) = -29
x+5+3x-7+9x+3-4x Collect like terms: 9x+1

Multiply by the reciprocal:48 / (3/5) = 48 x 5/3.Next, simplify, dividing 48 and the 3 in the denominator by 3. The result is:18 x 5/1which is equal to 90.Multiply by the reciprocal:48 / (3/5) = 48 x 5/3.Next, simplify, dividing 48 and the 3 in the denominator by 3. The result is:18 x 5/1which is equal to 90.Multiply by the reciprocal:48 / (3/5) = 48 x 5/3.Next, simplify, dividing 48 and the 3 in the denominator by 3.

5a^(3) if the x means multiplication. 5a^(3)x^(3) if the x is a variable.
If x = -7 and y = -3 then 5(-7) -2(-3) = -29
[(7+3)/(x+4)] / [(x-5)/(2-4)] =[(7+3)/(x+4)] * [(2-4)/(x-5)] =[10*(x-5)] / [-2*(x+4)] =-5*[(x-5)/(x+4)]
x-7.(-9)x-15
Step 1. 7 = 7x +2 Step 2. subtract 2 from both sides: 7 - 2 = 7x + 2 - 2 and simplify: 5 = 7x Step 3. divide both sides by 7: (5/7) = (7x/7) and simplify 5/7 = x x = 5/7 or about 0.714285
