Which expression completes the statement to form a true equation? 2 + 4² = a 2^5 b 9² c 2³ + 9 d 3² + 9

D

Step-by-step explanation:

the value of the given expression is

2 + 4² = 2 + 16 = 18

Hence we require to find the expression which equals 18

A = 32 ≠ 18

B 9² = 81 ≠ 18

C 2³ + 9 = 8 + 9 = 17 ≠ 18

D 3² + 9 = 9 + 9 = 18 → D is the equivalent expression

2 + 4² = 2 + 16 = 18

A. 2⁵ = 2 · 2 · 2 · 2 · 2 = 32

B. 9² = 9 · 9 = 81

C. 2³ + 9 = 2 · 2 · 2 + 9 = 8 + 9 = 17

D. 3² + 9 = 3 · 3 + 9 = 9 + 9 = 18

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
