Question

Evaluate
I worked it out as 36 as the answer but I do not know if that is correct. Please tell me.

Answer 1

Answer:

(3¹ × 9¹) + 3²  = 36

Step-by-step explanation:

(3¹ × 9¹) + 3² = (3 × 9)¹ + 3²

                    = 27¹ + 3²

                    = (3 × 3 × 3)¹ + 3²

                    = (3³)¹ + 3²

                    = 3³ˣ¹ + 3²

                    = 3³ + 3²

                    = 27 + 9

                    = 36

Yes, it is correct.
