Number of terms in the expression a² + bc × d is _______

Solution:

Number of terms in the expression a² + bc × d is two.

Given, a² + (bc × d) = a² + bcd

Two terms can be separated only by the operations of addition or subtraction.

✦ Try This: (i) Number of terms in the expression 2x + 3y + 7z is ________.

Number of terms in the expression 2x + 3y + 7z is 3

(ii) Number of terms in the expression (z - 2y)(z + 2y) is ________.

Given, (z - 2y)(z + 2y)

Using the identity (a +b) (a -b) = a² - b²

Here, a = z and b = 2y

∴  (z - 2y)(z + 2y) = z² - 4y²,

Hence, Number of terms in the expression (z - 2y)(z + 2y) is 2
