X ^ 2 - 9
= x ^ 2 - 3 ^ 2
It turns into 3 ^ 2
Because 3 ^ 2 = 9
The final answer is
= ( x + 3 )( x - 3 )
remember the formula :
a^2 - b^2 =(a+b)(a-b)
If the problem is
(17 ^ 3) * (79 ^ 7)
The steps are:
Step 1:
(17 ^ 3) = 4913
Step 2:
(79 ^ 7) = 1.92039E + 13
Step 3:
(4913) * (1.92039E + 13) = 9.43488E + 16
If the problem is
(173) * (797)
Step 1:
Multiply both terms with a calculator:
(173) * (797) = 137881
