That's pretty much a tricky question though
This equation has no solution where 'a' and 'b'
are both non-zero real numbers.
You said 2a + 2b = 2a
Subtract 2a from each side: 2b = 0
'b' must be zero.
And it doesn't matter what the value of 'a' is.
As long as b=0, 'a' can be any number.
First write out your original equation.

Then use the law of exponents(power of a power) to simplify.

(Multiply the numerator and denominator exponents by the outside power.)
The answer is 4 to the 21st over 5 to the 6th.

The easy way to do it would be to take it one step at a time.
To figure out the answer to this problem, you must first ask yourself this:
<span>
</span><span>How much is 126 of 700
</span> or
<span>What is 126 divded by 700
</span>
The answer is 0.18.
So, that means that 0.18 or 18 percent might be your answer.
Now, lets try 18 percent of 700, to see if we get 126.
<span>18% times 700
</span>
The anwer is 126.
SO:
$126 is 18 percent of 700.
18 percent of her sale is Destiny's commission.
