Question

Which of the following expression is true?

Answer 1

The second and fourth statements are true.

We have given that,

A). 4^3 x 4^5 < 4^12

B). 5^2 x 5^3 > 5^5

C). 3^2 x 3^4 = 3^2

D). 5^2 x 5^4 = 5^8

Now we have to determine the true statement.

$4^3 \times 4^5 < 4^{12}\\4^{15} < 4^{12}$

Therefore the first option is not true

5^2 x 5^3 > 5^5

$5^2 \times 5^3 > 5^5\\5^6 > 5^5$

Therefore the second option is correct.

$C). 3^2 \times 3^4 = 3^2\\3^6=3^2$

Which is contradiction

This statement is not true.

$D). 5^2 \times 5^4 = 5^8\\5^8=5^8$

This is a true statement.

Therefore the second and fourth statements are true.
