Answer 1

Solve it by BODMAS rule

16 + 81 = 97

Answer 2

Answer:

Algebra Examples

Rewrite x4 as (x2)2 ( x 2 ) 2 . Rewrite 81 as 92 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 - b 2 = ( a + b ) ( a - b ) where a=x2 a = x 2 and b=9 . Rewrite 9 9 as 32 3 2
