Answer 2

7 : 7 + 49 x (2³ x 15 - 4 x 5)

= 1 + 49 x (8 x 15 - 20)

= 1 + 49 x 100

= 149 + 1

= 150

Answer 3

7 : 7 + 49 x (2³ x 15 - 4 x 5)

= 1 + 49 x (8 x 15 - 20)

= 1 + 49 x 100

= 149 + 1

= 150

Answer 4

\(7:7+49\times\left(2^3\times15-4\times5\right)\)

\(=1+49\times\left(8\times15-20\right)\)

\(=1+49\times100\)

\(=1+4900\)

\(=4901\)
