B)
9f + 101 - 12f
Simply ​

-3f+101

Step-by-step explanation:

-3f+101

Step-by-step explanation:

collect like terms first

9f-12f+101

subtract now

9-12=-3

-3f+101

the nearest power is 1.651.

means 7482 to the 1.651th power is almost equal to 2489287

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
