What is sqrt (8^2+6^2) ?

c2 = 82 +62 c 2 = 8 2 + 6 2. Take the square root of both sides of the equation to eliminate the exponent on the left side. c = ±√82 + 62 c = ± 8 2 + 6 2. Simplify ±√82 +62 ± 8 2 + 6 2.

2011年5月29日 · 8减了2的一次方，也就是2，得到6,；6再减2的二次方，也就是4，得2；2再减2的三次方，也就是8，得-6；-6再减2的四次方，也就是16，得-22。 数字推理8，6，2，-6，（）-22。 二级等比数列题，6-8=-2； 2-6= -4； -6-2=-8-2，-4，-8 的等比级数为2，所以下一个数应该是（）—（-6）=-16可推算出为-22。

x^{2}-x-6=0 -x+3\gt 2x+1 ; line\:(1,\:2),\:(3,\:1) f(x)=x^3 ; prove\:\tan^2(x)-\sin^2(x)=\tan^2(x)\sin^2(x) \frac{d}{dx}(\frac{3x+9}{2-x}) (\sin^2(\theta))' \sin(120)

Rewrite the equation as x2 = 82 +62 x 2 = 8 2 + 6 2. Take the specified root of both sides of the equation to eliminate the exponent on the left side. Simplify ±√82 +62 ± 8 2 + 6 2.

1. Simplify the expression. Calculate any addition or subtraction, from left to right. How did we do? Please leave us feedback.

按时间（12进制）来计算，8+6=14点也就是2点，8-6=2点，24+6=0+6=6点，因此答案是6。

6.36解析分析算式可知:这是1~8连续8个数的平方,偶数的平方相加,奇数的平方相减;通过计算: 8^2-7^2=64-49=15=8+7, 6^2-5^2=36-25=11=6+5 ,…,可以看出,相邻两个数的平方之差等于这两个数的和;接下来将原式变形为相邻两个数的平方之差加相邻两
