Question

write the value of 5^2+log5^7​

Answer 1

Answer:

29.8927

Step-by-step explanation:

5² + log 5⁷

⇒ 25 + 7 log 5

⇒ 25 + 7 * 0.6989 = 25 + 4.892 = 29.8927

Answer 2

The value of $5^{2} +\log 5^7$ is equal to 29.8927.

Step-by-step explanation:

We have,

$5^{2} +\log 5^7$

To find, the value of $5^{2} +\log 5^7$ = ?

∴  $5^{2} +\log 5^7$

= 25 + 7 $\log 5$

Using the logarithm identity,

$\log a^m=m\log a$

= 25 + 7$\log 5$

= 25 + 7 × 0.6989 [ ∵ $\log 5$ = 0.6989]

= 25 + 4.892

= 29.8927

∴ The value of $5^{2} +\log 5^7$ = 29.8927

Thus, the value of $5^{2} +\log 5^7$ is equal to 29.8927.
