WebSolve for a (1/9)^(a+1)=81^(a+1)*27^(2-a) Step 1. Apply the product rule to . Step 2. One to any power is one. Step 3. Move to the numerator using the negative exponent rule . Step 4. Rewrite as . Step 5. Multiply the exponents in . Tap for more steps... Step 5.1. Apply the power rule and multiply exponents, . Step 5.2. Web2) Subtract one of the X terms from both sides. You can pick either one. Let's say you subtract 2x from both sides (this may be a little easier to work with a positive value as a result). - 14 = 2x - 16 3) To isolate the remaining X term, you need to add 16 to both sides: 2 = 2x 4) Then, complete the problem by dividing both sides by 2. 1 = x
Proof that $a(a+1)(2a+1)$ is divisible by $6$ for every integer a
WebJul 11, 2024 · a and (a+1) each have exactly 6 factors and a < 76. key here is : a and (a+1) are co-prime integer. Consider p, q, r, and s be 4 different prime numbers. for number of factors to be 6 a = p^2 * q (a+1) = r^2 * s as we have to find the value less than 76... substituting values will not take much of a time.... the only value comes up is a = 44 ... WebImagine this: There's an equation x = 2. Right now, x is only equal to two. Square both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x … true homes bryton
