Check out my math question brainliest to best !

You could do this step by step or all in 1 statement. I will do it step by step because that's the way I would teach it.

i1

i1 = 4 * (1/2)^(1 - 1)  Reduce the power

i1 = 4 * (1/2)^0   Change 1/2 to 1

i1 = 4 * 1 =     Multiply                                 4

i2

i2 = 4 * (1/2)^(2- 1)  Same directions as above

i2 = 4*(1/2)^1

i2  = 4*1/2 =                                                2

i3

i3 = 4 * (1/2)^(3 -1) Same directions as above.

i3 = 4 * (1/2)^2

i3 = 4 * 1/4

i3 =                                                             1

Total                                                           7    

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

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
