The square root of 25 is ___.相关知识点: 试题来源: 解析 5 25的平方根是指某个数乘以自身等于25。计算得:5 × 5 = 25,同时注意平方根在通常的数学定义下默认为非负数(主平方根)。因此,25的平方根为5。负数的平方(-5 × -5 =25)虽然也成立,但题目未明确要求列出所有可能解,因此答案为5。反馈 ...
Square root calculator – Step 2: We must be find the nearest perfect square below the selected group of the radicand, in the example 58). The result can not be greater than 58. After finding it, the digit is added to the root as the first digit of the result. In this case the n...
Related to square root:cube root,square root sign square root n. A divisor of a quantity that when squared gives the quantity. For example, the square roots of 25 are 5 and -5 because 5 × 5 = 25 and (-5) × (-5) = 25. ...
A square root is a number that equals the original number when multiplied by itself. When you raise a number to the power of 1/2, it is equivalent to multiplying it by itself. So, the expression "25^(1/2)" can be seen as "√25" and yields the same result of 5. How to ...
and we say "square root of 9 equals 3"Example: What is √25? 25 = 5 × 5, in other words when we multiply 5 by itself (5 × 5) we get 25 So the answer is: √25 = 5But wait a minute! Can't the square root also be −5? Because (−5) × (−5) = 25 too....
算子的平方根square root 线性算子 T∈L(V) 的平方根 R∈L(V) 满足R2=T。 并不是所有算子都有平方根,即使是复矢量空间中的算子也未必存在平方根。【习题8.A第6题】若 T∈L(C3), T(z1,z2,z3)=(z2,z3,0) ,若存在 R∈L(C3) 满足R2=T ,则有 C3=null (T3=0)=null R6=null R3=null ...
25,26,27,28,29. One of the parent sublattices, i.e., the honeycomb lattice, originally does not support any hinge states or flat-band states. The square-root operator, however, makes it inherit these exotic states from the other parent sublattice. When the square-root operation is ...
Five is the square root of 25. 五是二十五的平方根. 《简明英汉词典》 The square root of 144 is 12. 144的平方根是12. 《简明英汉词典》 The positive square root of the variance is called the standard deviation. 方差的正的平方根叫做标准差. ...
A square root of x is a number r such that r^2=x. When written in the form x^(1/2) or especially sqrt(x), the square root of x may also be called the radical or surd. The square root is therefore an nth root with n=2. Note that any positive real number h
A square root of x isa number r whose square is x: r2= x And we just found that: (+5)2= 25 (−5)2= 25 There aretwonumbers whose square makes 25 So both+5and−5are square roots of 25 Two Square Roots There can be apositiveandnegativesquare root!
