Answer:
Step-by-step explanation:
Rewrite log7(49)=x log 7 ( 49 ) = x in exponential form using the definition of a logarithm. If x and b are positive real numbers and b does not equal 1 , then logb(x)=y log b ( x ) = y is equivalent to by=x b y = x .
<span>Not included first digit (6), there are 7 digits so
62 500 000 = 6.25×10^7</span>
The answer is 25 because
5*5=25
