Answer:
x =
Step-by-step explanation:
(x + 6 )^2 = 49
get rid of the square , by square rooting the 49
x + 6 =
x = -6
x =
means + or - hence it could be -7 -6 = -1 ... or 7-6 = 1
therefore the answer is = or - 1
hence in terms of roots .. answer is :
Remember that finding terms in a geometric sequence is done by multiplying the previous term by a common ratio . For example, we can say:
We have . To find
, let's multiply this term by
:
Now, let's use this to find all of our other terms:
Thus, our terms are 64, 80, 100, 125, and (625/4).
So the rule with multiplying exponents of the same base is . Apply this rule here:
Next, the rule with converting negative exponents into positive ones is . Apply this rule here:
<u>Your final answer is 1/49.</u>
<h2>------------------------------------------------</h2>So an additional rule when it comes to exponents is
In this case, your fractional exponent, x^9/7, would be converted to . However, I had just realized you can further expand this.
Remember the rule I had mentioned earlier about multiplying exponents of the same base? Well, you can apply it here:
Your final answer would be
