Answer:
The correct option is 1/4^2
Step-by-step explanation:
The given expression is:
4^6 * 4^-8
According to the same base rule if the exponents have the same base then the exponents will be added.
If we look at the given expression both the values have the same base.
Therefore we will add the exponents of the value.
= 4^6+(-8)
= 4^6-8
= 4^-2
Now to change the negative exponent into positive we will take it to the denominator.
4^-2 = 1/4^2
Thus the correct option is A....
7x^2+x+9 - (<span>3x^2+4x-5)
= </span>7x^2 + x + 9 - 3x^2 - 4x + 5
= 4x^2 - 3x + 14
