Which exponential equation is equivalent to the logarithmic equation below?
log 987=a
a. 987^10=a
b. 10^a=987
c. a^10=987
d. 987^a=10

Step-by-step explanation:

Given :

To Find: Which exponential equation is equivalent to the logarithmic equation below?

Solution:

---1

Now using property :

So, comparing 1 with property

Thus Option B is correct.

Hence exponential equation is equivalent to the logarithmic equation below

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
