Solving Exponential Equations (lacking a common base) 31^d=38

Bond [772]

Answer:

d = log 38/log31

d = 1.06

Step-by-step explanation:

31 ^ d = 38

Take log of both sides since the exponential equation have different base (always)

d log 31 = log 38

d = log 38 / log 31

d = 1.58 / 1.491

d = 1.06.

We can actually check to see if this is correct.

Substituting d = 1.06

31^ 1.06 = 38.092

(You see, that's approximately correct)

melomori [17]

Answer: Expression in terms of p and b for the total number of batteries bought by Jonathan is given by

$8p+25b$

Step-by-step explanation:

Since we have given that

Each packet contains 8 batteries.

Each box contains 25 batteries.

Let number of packets be p

Let number of boxes be b

So, According to question,

$8p+25b$

Hence, Expression in terms of p and b for the total number of batteries bought by Jonathan is given by

$8p+25b$
