Answer 2

The unit place of $2^9^0\times3^4^5$ = 6

Given:

$2^9^0\times3^4^5$

To find:

The unit place of $2^9^0\times3^4^5$

Concept used:

If unit digit number are 2,3,4 then the power of the number is repented in the form of multiple of 4

Explanation:

If unit digit number are 2,3,4 then the power of the number is repented in the form of multiple of 4.

That is,

Unit digit of $2^9^0$ = $(2^4)^2^2$ × 2²

                         = $2^4$ × 2²

                         = 16×4

Unit digit of $2^9^0$ = 4

Similarly Unit digit of $3^4^5$ = $(3^4)^1^1$ × 3

                                        = 3 × 3

                                        = 9

The unit place of $2^9^0\times3^4^5$ = 4 × 9 = 6

The unit place of $2^9^0\times3^4^5$ = 6.
