Step-by-step explanation:
<u>Radical As A Fractional Exponent
</u>
We can write a radical as a fractional exponent. The power to which the base is raised is the numerator and the root is the denominator. For example, the radical
is equivalent to
A) The simplification shown in the image is wrong because the student subtracted the roots of the radicals separated from the subtraction of the powers.
B) The correct procedure is
* Express both radicals as fractional exponents
* Subtract both exponents
* Simplify the resultant fraction
* Return the fractional exponent to radical form
In our case, the correct procedure is
Answer:
option B is correct because
1 hectameter is equal to 10000cm
4(x-2)+3=2x-9
4x-8+3=2x-9
4x-5=2x-9
4x-5+5=2x-9+5
4x=2x-4
x = -2
The odd one out would have to be 7:41 because 7x6 is 42 which is the pattern thats happening
