Question

(71)2 and (17)2 using identity find the values of full solution

Answer 1

Answer:

71^2=(70+1)^2 use (a+b)^2 to solve it

17^2=(20-3)^2 use (a-b)^2 to solve it

Answer 2

The final answer is "5041" and "289".

Step-by-step explanation:

$\ Given \ value:\\\\(71)^2 \ and \ (17)^2 \\\\\ find:\\\\\ identity=?\\\\\ Solution:\\\\i) (71)^2 = (70+1)^2\\\\ii) (17)^2 = (20 -3)^2\\\\\ formula:\\\\(a+b)^2 = a^2+b^2+2ab\\\\(a-b)^2 = a^2+b^2-2ab\\\\ i) (70+1)^2 = (70)^2 + (1)^2+ 2(70)(1)\\\\\rightarrow 4900+1+140\\\\\rightarrow 5041\\\\ii) (20-3)^2 = (20)^2+(3)^2-2(20)(3)\\\\\rightarrow 400+9-120\\\\\rightarrow 289$
