Question

Using identities, evaluate:
169^2-131^2​

Answer 1

Step-by-step explanation:

${a}^{2} - {b}^{2} = ( a+ b)(a - b) \\ {169}^{2} - {131}^{2} = (169 + 131)(169 - 131) \\ (300)(38) \\ = 11400$

Hope it helps!!!

Answer 2

Answer:

11,400

STEPS:

169^2=28561

131^2=17,161

169^2-131^2= 28561 - 17161

=) 11400
