Question

Which of the following is not true?

• A. $3^2>2^3$
• B. $4^3$ = $2^6$
• C. $3^3\ne 9$
• D. $2^5>5^2$

Answer 1

The correct option is C $3^3\ne 9$

$3^2$ > $2^3$
$\Rightarrow 9>8$ is true.
$4^3$ = $2^6$
since, $4^3=64$ and $2^6=64$
$4^3$ = $2^6$ is true.
$4^3>3^4$
$4^3$ = 64 and $3^4=81$
Hence, $4^3<3^4$, so the given statement is false.
$2^5$ > $5^2$
$\Rightarrow 32>25$ is true.
