12. 2*5 = 83325;4*6 = 6410036, 3*7 = 277649
then 5*9 =​

Answer 1

Given:-

• 2*5=83325
• 4*6=6410036
• 3*7=277649

To Find:-

• 5*9=?

Solution:-

• At 1st we have to find cube of 1st factor after that square of 2nd factor than add both after that write it after 1st factor of cube after that write the square of 2nd factor.

=>Logic used here

=>2*5=83325

=>2³=2×2×2=8(write 1st)

=>5²=5×5=25

=>2³+5²=8+25=33(write 2nd)

=>5²=5×5=25(write 3rd)

The required number=83325

=>4*6=6410036

=>4³=4×4×4=64(write 1st)

=>6²=6×6=36

=>4³+6²=64+36=100(write 2nd)

=>6²=6×6=36(write 3rd)

The required number=6410036

=>3*7=277649

=>3³=3×3×3=27(write 1st)

=>7²=7×7=49

=>3³+7²=27+49=76(write 2nd)

=>7²=7×7=49(write 3rd)

The required number=277649

Similarly:-

=>5*9=?

=>5³=5×5×5=125(write 1st)

=>9²=9×9=81

=>5³+9²=125+81=206(write 2nd)

=>9²=9×9=81(write 3rd)

The required number=12520681

Hence,

• The value of 5*9=12520681
