Which of the following is not true
a. 3² > 2³
b. 4³ = 2⁶
c. 3³ = 9
d. 2⁵ = 5²

Solution:

We have to determine the true statement from the given options.

Considering 3² > 2³,

3² = 3 × 3

= 9

2³ = 2 × 2 × 2

= 8

3² > 2³ = 9 > 8

Therefore, option a is true

Considering 4³ = 2⁶,

4³ = 4 × 4 × 4

= 64

2⁶ = 2 × 2 × 2 × 2 × 2 × 2

= 64

Therefore, option b is true

Considering 3³ = 9,

3³ = 3 × 3 × 3

= 27

3³ = 27

Therefore, option c is not true.

Considering 2⁵ = 5²,

2⁵ = 2 × 2 × 2 × 2 × 2

= 32

5² = 5 × 5

= 25

2⁵ ≠ 5²

Therefore, option d is not true.
