Product rule:


Power rule:

The exponential function is its own derivative:

Assuming the base of
is
, its derivative is

But if you mean a logarithm of arbitrary base
, we have



So we end up with


Answer:
49
Step-by-step explanation:
When Karen was born, the dad is 22 so Karen is now 27 which means the dad is 22+27= 49
1/4 is equal to 0.25
1/10 is equal to 0.10
so no, 1/4 is not less than 1/10

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to combine the like terms
From given expression,

By distributive property,
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
a(b + c) = ab + bc
Therefore,
Solve for brackets using distributive property

Add 1/7 and 6/7

Thus the equivalent expression is found
