Question

(3⁵.3⁷):3¹⁰+5.2⁴-7³:7

Answer 1

`(3^5 . 3^7):3^(10)+5. 2^4-7^3:7`

`= 3^(12):3^(10)+5. 2^4-7^(3-1)`

`= 3^(12-10) +5. 2^4-7^2`

`=3^2 +5.  16-49`

`=9 +5.  16-49`

`=9+ 80-49`

`= 89 -49`

`=40`

Answer 2

(3⁵.3⁷):3¹⁰+5.2⁴-7³:7

=3¹²:3¹⁰+5.16-7²

=3²+80-49

=9+80-49=89=49=40

Answer 3

\(\left(3^5.3^7\right):3^{10}+5.2^4-7^3:7\)

\(=3^{12}:3^{10}+5.16-7^2\)

\(=3^2+80-49\)

\(=9+80-49\)

\(=40\)
