Answer:

Option (D)

Explanation:

Given expression is,

x³ × 3 ÷
(2)/(9) + 9x - (7 - 6x)

By substituting x =
(2)/(3),


((2)/(3))^3* 3 / (2)/(9)+9((2)/(3))-[7-6((2)/(3))]

By using rule PEMDAS,

P - Parenthesis

E - Exponent

M - Multiplication

D - Division

A - Addition

S - Subtraction


=((2)/(3))^3* 3 / (2)/(9)+9((2)/(3))-[7-4]

=
((2)/(3))^3* 3 / (2)/(9)+9((2)/(3))-3

=
(8)/(27)* 3 / (2)/(9)+6-3

=
(8)/(9)/ (2)/(9)+6-3

=
(8)/(9)* (9)/(2)+6-3

= 4 + 6 - 3

= 7

Option (D) is the answer.
