Question

8 X 6=28, 11 X 5=96, 15X 7=?

Answer 1

Answer:

Your answer is 176

Step-by-step explanation:

(8)^2 - (6)^2 =. 64 - 36 = 28

(11)^2 -(5)^2. =. 121 - 25 = 96

(15)^2 - (7)^2. =. 225 - 49 = 176

Answer 2

The value of missing number (?) = 176

Step-by-step explanation:

We have,

8 × 6 = 28, 11 × 5 = 96

To find, the value of 15 ×  7 = ?

The pattern follow:

$(First number)^{2} -(second number)^{2}=R.H.S. (Number)$

8 × 6 = 28

28 = $8^{2} -6^{2}$ = 64 - 36 = 28

11 × 5 = 96

96 = $11^{2} -5^{2}$ = 121- 25 = 96

Similarly,

? = $15^{2} -7^{2}$ = 225 - 49 = 176

∴ The value of missing number (?) = 176
