If 5=5,6=12,7=21,8=32, then 9 is equal to
Compute the required value
Given that 5=5,6=12,7=21,8=32
Hence the given data can be written as
5×1=56×2=127×3=218×4=32
so 9×5=45
Hence the value of 9 is 45
Verify the following :
(i) 37×(56+1213)=(37×56)+(37×1213) (ii) −154×(37+−125)=(−154×37)+(−154×−125) (iii) (−83+−1312)×56=(−83×56)+(−1312×56) (iv) −167×(−89+−76)=(−167×−89)+(−167×−76)
Find
(i) (ii) (iii)
(iv) (v)
